Whether you’re a carry-on-only kind of person or not , knowing the Transportation Security Administration’s (TSA) liquid limits is essential for anyone who travels by plane in the United States. Yet understanding which of your toiletries, foods, and other items even count as “liquid”—let alone how best to pack them—can get confusing. Use this guide to understand the TSA’s rules and restrictions about liquids, common exceptions, and tips to help ensure your next airport security screening goes smoothly.

What is the TSA liquid limit?

The TSA’s liquid limit for carry-ons—known as the 3-1-1 rule—allows travelers to pack liquids, aerosols, gels, creams, and pastes under 3.4 ounces (100 milliliters) in their carry-on bags. Passengers are allowed up to one quart-sized bag per person , or roughly nine 3.4-ounce containers in a single quart-sized bag. Anything more will have to go in a checked bag or risk being tossed out.

If your liquids are stored in containers larger than 3.4 ounces, even if there’s only 3.4 ounces left inside the bottle, you can’t bring them through security.

Completely empty bottles, such as your reusable water bottle , are allowed through the TSA checkpoint since (spoiler alert!) they don’t contain any liquids at that moment.

Which toiletries TSA allows in your carry-on

The TSA allows all of the following common toiletries in your carry-on only in containers that are 3.4 ounces or less:

  • Shampoos and conditioners
  • Lotions and sunscreen
  • Gel hair products

In other words: yes, you can bring toothpaste, deodorant, and sunscreen through TSA checkpoints but only if they are in travel-sized containers.

Powders and powder-like substances, including baby powder and some makeup items, aren’t restricted in your carry-on bag. But if you’re carrying more than 12 ounces (350 milliliters) of a powder, you’ll need to place it in a separate bin for X-ray screening, and it may be subject to additional screening—so it’s a good idea to budget an extra few minutes at the security checkpoint if you think this might happen.

Tips for packing your toiletries in your carry-on

To comply with TSA regulations, invest in small, reusable toiletry bottles, like these capsules by Cadence.

Especially if you don’t have TSA PreCheck , it’s helpful to pack all of your toiletries in a quart-sized (or smaller) clear plastic toiletry bag for screening. Although improved airport technology means that far fewer air passengers (both in PreCheck and non-PreCheck lines) will have to take their liquids out out of their carry-on, it’s still helpful to have all of your liquids in one bag just in case you get pulled aside for additional screening. For an upgrade from that large Ziplock, we recommend the standard-sized Clarity Jetset Case from Truffle ($88), which has a clear window panel and is comparable in size to a quart-sized bag.

Since toothpaste is considered a liquid, paste, or gel by the TSA, most of us toss those tiny one-ounce tubes in our carry-on bags. However, if you want to ditch the hard-to-recycle packaging, consider toothpaste tablets, an ecofriendly alternative that’s not subject to the 3-1-1 rule. We like Humankind’s fluoride toothpaste tablets ($12), which resemble small mints and turn to paste when you crush them between your teeth. Matador has also recently released a reusable toothpaste tube ($10), which you can fill (and refill) with your regular toothpaste.

For travel toiletries that are easy to rebottle (like shampoo or body wash), consider investing in reusable bottles or containers so you can always keep your preferred brand on hand. Some of our favorite TSA-approved toiletry bottles include:

These easy-to-fill, leakproof silicone tubes are ideal for shampoos, conditioners, lotions, and body washes. GoToob’s line comes in a variety of sizes, ranging from 1.7 to 6 ounces, and are easy to clean between refills.

Each three-ounce, TSA-approved bottle is made from a durable, waterproof, nylon-based fabric.

The refillable travel containers by Cadence are small, leakproof “capsules” that click together with magnets. At 0.56 ounces, they’re best for makeup and toiletries you don’t need much of—like a weekend’s worth of shampoo or a week of that under eye cream you only need a dab of.

Foods are subject to liquid limits

The TSA’s 3-1-1 rule applies to food too, meaning you’ll need to make sure any foods that count as liquids, gels, or pastes (like yogurt, peanut butter, pâté, jams, or that tasty pimento cheese spread you tried to bring home from Charleston) are less than 3.4 ounces or packed in your checked bag. There are some exceptions, like frozen foods and juice for babies, and the TSA’s website is the best resource to check for specific items.

Exceptions to TSA’s liquids rule: Full-sized liquids that you can bring through security

The TSA has several important exemptions to its liquids rule. You’re allowed to bring full-sized bottles of the following:

Hand sanitizer: Due to the coronavirus pandemic, the TSA currently allows travelers to bring up to 12 ounces of hand sanitizer in their carry-on bags. These will be screened separately.

Medication: You’re allowed to bring medically necessary liquids, aerosols, and gels through security. This also includes the ice or gel packs you may need to keep your medications cool. You are not required to store these items in a plastic, resealable bag, but you should remove them from your luggage and let the TSA officer know what you’ve packed.

Baby formula and breast milk: Like medication, you can bring freezer packs to keep these items cool, and you should remove them from your luggage and notify an agent when you go through security. More baby-related exceptions? Gel or liquid-filled teethers and canned or jarred baby food.

Of course, the final decision on whether an item is allowed through the checkpoint rests with the TSA officer.

If you’re ever unsure about a specific item, the TSA’s website has a handy, searchable list of prohibited and allowed items worth checking before you travel. You can also now text the TSA with your questions.

Here's the 411 on the TSA's 3-1-1 liquids rule

Samantha Rosen

We've all been there. Waiting in the Transportation Security Administration line only to hear agents call for a "bag check," often because a traveler had a liquid product in their carry-on that's over the allowed limit (or some sort of other prohibited item).

It's a process that can sure slow things down, particularly on the busiest travel days. As you pack for your trip and consider what to put in your carry-on or checked luggage, it's important to consider what the TSA's limits are for liquids and similar products.

Since September 2006, the TSA has gone by the 3-1-1 rule when it comes to those types of products, including items like toothpaste, shampoo, conditioner, mouthwash and lotion -- sunscreen included.

For more TPG news delivered each morning to your inbox, sign up for our daily newsletter .

In short, the 3-1-1 rule is: Each liquid you bring through the TSA checkpoint must be in a 3.4-ounce or smaller container ("3"), all containers must be placed inside one clear quart-size plastic bag ("1") and each passenger is only allowed one plastic bag ("1").

air travel max liquid size

If you meet those requirements, you should get through security without issue. However, if your liquid items are larger than 3.4 ounces each, you'll have to leave them in your checked bag.

air travel max liquid size

There are a few exceptions, though.

The TSA has kept in place a temporary pandemic exception to the rule, allowing up to 12 ounces of liquid hand sanitizer in carry-on baggage.

Part of this exception: The hand sanitizer will have to be screened separately since it's technically over the limit. You'll need to remove it from your bag before it goes through the scanner.

There are also exceptions for larger amounts of medically necessary liquids, gels and aerosols. You can bring those products in larger, "reasonable" quantities, the TSA's website says. However, you must declare those items to security officers at the checkpoint for inspection.

This could, obviously, take a little more time than if you're traveling without those items.

This exception doesn't include sunscreen, despite calls to relax sunscreen restrictions at TSA checkpoints. Like other liquid products, sunscreen bottles over 3.4 ounces must go in your checked luggage.

There are also many liquids you cannot bring with you .

You can bring creamy cheeses, liquid chocolate, liquid coffee, creamy dips and spreads, gravy, honey, hummus, ice cream, jam, jelly, juice, syrup, peanut butter, salad dressing, sauce, salsa, soda, soup and yogurt as long as they are in a container of less than 3.4 ounces according to the TSA .

Related: Should you get TSA PreCheck or Clear — or both?

And yes, you can bring your water bottle with you, even if it weighs more than 3.4 ounces — as long as it's empty. This can also be a great way to save money at the airport, since -- as the TSA points out -- many airports have filling stations for reusable water bottles.

When in doubt, consult the TSA's list of what you can carry through the airport and check with your airline.

TSA Liquids Rule Explained: What Size Liquid Can You Bring on a Plane?

' src=

What you can and can’t bring on a plane, including the amount allowed, can be very confusing for even the most experienced of flyers, especially when it comes to liquids.

According to TSA regulations, you are allowed to bring liquids in containers that don’t exceed 3.4oz/100ml in your carry on.

There are also limits when liquids are packed in your checked bags, which many people are not aware of, though the limits are much greater.

What Size Liquid Can You Take on a Plane?

Carry on bags.

The TSA has a rule in place called the 3-1-1 Rule .

The 3-1-1 Rule states that “each passenger may carry liquids, gels and aerosols in travel-size containers that are 3.4 ounces or 100 milliliters .”

These containers must also fit in a 1-quart sized, resealable bag.

You are required to take this bag out of your carry on and place it in a screening bin as you go through airport security.

Note that it is the size of the container itself and not how much liquid is in the container that matters.

So, if you have a bottle that contains just 1ml of liquid inside a 4oz container, it still won’t be allowed through.

Checked Bags

Not many passengers are aware that there are restrictions on the quantity of liquids you can pack in their checked bags.

According to the TSA:

  • A container must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces).
  • The total aggregate quantity of your toiletry products must also not exceed 2 kg (70 ounces) or 2 L (68 fluid ounces).

No Differences For International Flights

Even though it may not be called the 3-1-1 rule worldwide, the rules remain the same if you’re flying internationally.

So regardless if you’re flying from or within Mexico, Canada, the UK, Europe or any other country, you are only allowed to pack liquids (as well as gels and aerosols) in containers that are no larger than 3.4oz/100ml in your carry on.

Airlines Follow TSA Regulations

All airlines follow TSA regulations .

So this means that regardless if you’re flying with Delta, Southwest, American Airlines, JetBlue, or any other regional or major air carrier worldwide, you are only allowed to bring liquids in containers that do not exceed 3.4oz/100ml in your carry on.

How to Pack Liquids for Flying

There are a few guidelines you should follow to make your next flight go as smoothly as possible.

  • Make sure that no container you want to bring is no larger than 3.4oz/100ml.
  • Buy travel-friendly products of your favorite products.
  • If the company doesn’t sell travel-friendly sizes, buy your own 3.4oz/100ml containers and transfer the liquids into them.
  • Consider packing non-liquid alternatives instead (you can bring a bar of soap on a plane on a plane , for example, with no restrictions. The same applies to sunscreen sticks ).
  • Share toiletry space with your travel partner, as the 3-1-1 Rule applies to each passenger.
  • Store your items in a clear bag that is no larger than 1 quart.
  • Use your checked luggage for liquids in larger containers.

You Will Be Able to Bring 7-8 Bottles in Your Carry On

In total, you can take 32 ounces (or 1 quart) of liquids on a plane.

But as the containers themselves will take up space in the single quart-sized bag, you won’t be able to take a full 32 ounces of liquids in your carry on.

You will be able to bring about 25 ounces in total, in 7 or 8 travel-sized 3.4oz/100ml containers onto a plane in your carry on.

How Many Ounces in Total Can You Take On a Plane?

Carry on bags.

As just mentioned, you can bring 32 ounces (or 1 quart of liquids on a plane), though it will more likely be 25 ounces in 7-8 bottles.

If liquids are packed in your checked bags, each container must not exceed 18 ounces or 17 fluid ounces).

The total aggregate quantity of your toiletry products must also not exceed 70 ounces or 68 fluid ounces.

A Loophole to Bring More Than 3.4 Oz/100ml On a Plane

There is a loophole that lets you bring more than 3.4oz/100ml of liquids on a plane, though it only works with very few items and under certain circumstances.

If you are traveling with a young child or baby, you can say that the item is for them.

Of course, this will only work for bringing a water bottle on a plane and not items like alcohol, coffee or tea . 

Exceptions to the 3-1-1 Rule

There are several exceptions to the 3-1-1 Rule.

The following items, if packed in your carry on bags, are allowed to exceed 3.4 oz/100ml:

  • Breast milk and formula
  • Liquid medication
  • Hand sanitizer
  • Jumbo disinfecting wipes
  • STEB items (secure, tamper-evident bags purchased at the airport)
  • Cough syrup
  • Gel-filled bras
  • Saline solution
  • Ice packs (must be frozen solid)

Liquids That Are Forbidden

There are several liquids that, even if under 3.4 oz/100ml, you are not allowed to bring on a plane in either your carry on or checked bags.

These items include:

  • Most flammable liquids ( you can bring nail polish on a plane , though)
  • Most toxic liquids
  • Aerosols that do not qualify as toiletries
  • Alcoholic Beverages over 70% ABV (140 proof)
  • Insecticide
  • Spray Paint
  • Spray Starch
  • Cooking Spray

Surprising Items That Qualify As Liquids

There are also items that you wouldn’t expect to count as liquids, but actually do.

  • Peanut butter
  • Hair mousse
  • Snow globes

What the 3-1-1 Rule Stands For

The 3-1-1 Rule stands for 3 ounces, 1 passenger, 1 quart-sized bag.

While the limit is actually 3.4 ounces instead of 3 ounces, we guess that 3.4-1-1 Rule didn’t have the same ring to it.

Why the 3-1-1 Rule Exists

The 3-1-1 Rule exists because terrorists have previously tried to sneak liquid explosives on a plane on more than one occasion.

While the rule is frustrating, it exists for the safety of passengers.

Liquids Allowed in Carry-On Luggage

air travel max liquid size

If you're taking a flight for your vacation, you need to know the quantities and types of liquids that the Transportation Safety Administration (TSA) allows passengers to bring onto an airplane in their carry-on luggage .

While good security is essential, TSA's regulations on liquid quantities certainly make it harder to take some necessary items on planes. Today’s travelers have to pay attention to exactly what they’re carrying, especially when it comes to shampoos, shaving cream, drinks, and anything resembling a fluid, as many of the TSA's rules forbid these items in certain quantities.

The TSA and airport screeners are strict about the amount and type of liquids that travelers can take with them on the plane. However, they've fortunately developed a handy guide to help passengers prepare for their trip. Known as the 3-1-1 rule for carry-on liquids, this rule states that most liquids, gels, and aerosols can be transported as long as each item is in a 3.4-ounce or smaller container and all items fit in a single one-quart plastic zip-top bag.

The 3-1-1 Rule

According to the 3-1-1 guidelines, travelers, in general, are allowed to bring on most liquids, from shampoo to hand sanitizer gels, as long as they meet the requirements of the 3-1-1 rule. Typically this means you can carry up to six 3.4-ounce bottles of shampoos, contact solution, and other liquid necessities as long as they are all contained within a zip-top bag.

You can also put liquids in your checked luggage (as long as they’re not prohibited items). However, if you do this, you should make sure the liquids are sealed really well so that they don't come up while being transported beneath the aircraft. The last thing you need on a business trip is to have your shampoos or other liquids leak all over your business suit or wardrobe. Fortunately, there are plenty of great TSA-approved travel toiletry bottles available to choose from.

Special Liquids and Larger Quantities

Travelers can also declare larger containers of selected liquids, such as baby formula or medications , at the checkpoint. Airport screeners will generally allow them in moderate quantities, and declared liquids don’t have to be in zip-top bags.

Medications, baby formula and food , and breast milk are allowed in reasonable quantities exceeding three ounces, but you'll need to declare these items for inspection at the checkpoint. Also, it's worth noting that TSA screeners do allow you to bring ice through the security checkpoint as long as it's frozen solid. So if you bring ice, make sure to dump out any water before you hit the security checkpoint.

Examples of liquids that can be in excess of the 3.4-ounce rule include:

  • Baby formula, breast milk, and juice (for babies)
  • Both prescription and over-the-counter medications
  • Liquids or liquid nutrition for people with disabilities or medical conditions
  • Specialized medical liquids like contact solution
  • Frozen items, if they’re frozen solid
  • Medical or cosmetic items with liquid or saline

If you’re attempting to bring one of the above items with you, the TSA requires you to separate them, declare them to a security officer, and present them for additional screening. For complete information on the 3-1-1 rule, visit the TSA website, and for a complete list of prohibited items, visit the official TSA prohibited items list.

Why the TSA Limits Liquids

While it may seem like an arbitrary rule to some, the TSA 3-1-1 Rule actually took a considerable amount of negotiation and research to implement and was developed in response to an attempted attack on an airport in the United Kingdom.

On August 10, 2006, authorities in the United Kingdom arrested a group that was planning to destroy a number of airplanes by using an explosive mixture of a sports drink and other chemicals. After the arrest, the TSA rigorously tested a wide variety of liquids to determine which should be banned outright and what quantity of common household liquids was safe for passengers to bring aboard.

The United States adopted the 3-1-1 Rule in September of 2006, and the TSA screens all arriving international flights to make sure passengers comply with domestic regulations. Other countries have since adopted the same or similar regulations in order to ensure uniform administration of safety rules around the world. Canada, China, South Korea, New Zealand, Australia, and all member states of the European Union follow the 3-1-1 Rule.

We've all fallen victim to TSA while traveling; here's a refresher so you don't make the same mistakes again.

TSA Liquid Rules:

According to the TSA website , these rules apply for liquids, aerosols, gels, creams, and pastes.

All liquids must be in a 3.4oz or smaller container. Your serums, creams, cleansers, and masks are too expensive to lose, so check their sizes and if they're too big, leave them at home or transfer them to a smaller container.

They have to be able to fit in a quart-size bag. Before you throw 10 containers of liquids into your carry-on, make sure that everything can fit in a quart-size bag. Think about what you really need for your trip, a la Marie Kondo , and remember you can always buy things once you arrive at your destination.

Powders must be in 12oz containers or smaller. TSA placed new restrictions on powders in 2018. Ensure that your makeup, protein powder, and baby powder are in containers within that range, or put them into a checked bag.

Anything else has to go into a checked bag. If you can't part with your full-size products, they have to go into a checked bag to avoid getting tossed into the TSA product graveyard. If you're looking to save money, share one checked bag with your whole group.

Only empty water bottles will pass the TSA checkpoint. If you bring a refillable water bottle, make sure it's empty before you approach security. You can fill it up after you go through the checkpoint or buy water in the terminal.

There are exemptions. If you use a medication that comes in liquid, aerosol, gel, cream, or paste form and the container is larger than 3.4oz, it's exempt from the above rules. Similarly, if you're carrying baby formula, breast milk, or other liquid foods for your child, these are also exempt.

Everything You Need to Know About TSA Liquid Rules

Here's what to know before you fly with shampoo, medication, or any other liquids you may need during your travels.

air travel max liquid size

Dealing with airport security can be one of the more daunting aspects of air travel , from the detailed rules about what you can and can't bring on board to the long lines that often form at checkpoints.

One rule that frequently trips up travelers is the Transportation Security Administration's (TSA) 3-1-1 regarding liquids in carry-on bags . We're here to walk you through the finer details of the rule and provide helpful tips for packing liquids when you're flying.

What is the TSA's 3-1-1 rule?

In 2006, British security officials thwarted a plot to bomb an aircraft with liquid explosives carried on board. Since then, security agencies around the world have limited the amount of liquid passengers can bring through airport security.

For the TSA, which regulates travel in the United States, all liquids, gels, and aerosols must be in containers that are 3.4 ounces (100 milliliters) or less. All liquids must fit into a single, clear quart-size bag — passengers can only pack one of these bags in their carry-on.

The 3-1-1 designation is a simple way to remember these numbers: individual liquid containers must be 3.4 ounces or smaller, they must fit into one clear, quart-size bag, and there is only one bag allowed per passenger.

Liquids that do not comply with the 3-1-1 rule must be packed in checked bags, or thrown out at airport security. Some liquids, such as gasoline or other flammable liquids, are prohibited entirely, both in checked and carry-on bags. You can find a full list of permitted and prohibited items on the TSA's website .

If you're unsure if a specific item adheres to the 3-1-1 rule, you can always contact the TSA before your trip. "Tweet your questions and comments to @AskTSA or via Facebook Messenger , weekdays from 8 a.m. to 6 p.m. ET," TSA spokesperson Jessica Mayle tells Travel + Leisure . "You can also call the TSA Contact Center at 866-289-9673."

Are there any exceptions to the 3-1-1 rule?

The TSA does exempt some items from the 3-1-1 rule: medically necessary liquids, formula, and breast milk. You can bring more than 3.4 ounces of these liquids on board, but you may have to undergo additional security screening.

"Inform the TSA officer at the beginning of the screening process that you're carrying them," says Mayle. "These liquids are typically screened by X-ray, but TSA officers may also test them separately for explosives or concealed prohibited items. Officers may ask you to open the container and/or have you transfer a small quantity of the liquid to a separate empty container, or dispose of a small quantity, if feasible."

If you don't want your exempt liquids to be screened by X-ray, inform your TSA officer, and they will use alternative security measures to clear the items.

And that's not all. "There's an exception for hand sanitizer, which has a temporary 12-ounce limit," says Mayle. But as COVID-19 travel restrictions and protocols continue to lift, the temporary special case for hand sanitizer could change, too.

Another exception is liquids purchased after security in an airport. In domestic U.S. airports , you can bring nonalcoholic drinks and other liquid items purchased airside onto your flight. (This is not always the case in international airports.) Duty-free liquids, however, will be sealed in a tamper-safe bag before boarding — sometimes they're permitted in the cabin, and other times they may be stowed elsewhere on the plane.

Packing Tips for Liquids in Carry-on Bags

  • While many products are sold in 3.4-ounce containers suitable for travel, not all of them are. Consider rebottling your liquids into travel-size, leak-proof cases.
  • "Another way to save space in your quart-sized bag is to pack solid versions of products, which you can put in your luggage or carry-on bag without needing to place it in the quart-size bag," travel advisor Ateet Ahuja of Complete Getaways tells T+ L. "For example, you can bring a stick or solid version of some perfumes and shampoo bars instead of liquid shampoo."
  • Buy your liquids, like shampoo or mouthwash, at your final destination. "While you'll spend a little extra, the cost far outweighs the potential of it spilling or leaking in your bag," says Ahuja.
  • On that note, prepare for spills — Ahuja advises wrapping a small hand towel around your quart-size bag.
  • Pack your nonliquid toiletries separately to save space in your quart-sized bag.
  • Pack your liquids bag in an easy-to-access space, like an external compartment or the top of your carry-on bag. According to Ahuja, "This will save you time in the TSA line."

Maximum Liquid You Can Take on a Plane in Carry On?

John Parker

It can be quite confusing to know what the carry on bag liquid limit is and also what is considered to be a liquid under the Transportation Security Administration (TSA) 311 rule.

By following the TSA liquids rules you will pass through airport security much quicker and with fewer problems. You will also ensure that you don’t have any expensive toiletries etc taken away from you.

Hopefully, this article will thoroughly explain the carry-on liquid limits and clarify them so you don’t break the TSA regulations.

maximum liquid carry-on airplane

The Quick Answer: The TSA rules for flying with liquids specify that liquids on planes must be in containers that are no larger than 3.4oz/100ml each in order to be taken through airport security. All the liquids you are carrying must fit into one quart-sized resealable plastic bag.

Carry on liquid size policy?

The TSA uses what it calls the 311 rule.

The description of the 311 rule is a little tenuous as the 3 isn’t entirely accurate. What it means is quite easy to understand, though:

The carry on liquid size of 3.4 ounces (100 ml) refers to the maximum size of the container, not necessarily the amount of liquid held in it. So, for example, you cannot take a container of deodorant that held 6 ounces when full but is now less than half full.

If traveling to or within Europe, the allowable size for your bag of liquids is 1 liter. This is slightly larger than one quart, so if you have a TSA-approved quart-sized bag, you will be fine.

You can buy an approved liquids bag on Amazon relatively cheaply and some come with empty travel-sized containers to put liquids in – TSA 3-1-1 Approved Clear Airline Carry On Bag

Larger liquid containers must go in your checked bag. See How much liquid can you take on a plane in checked baggage?

What to do with your liquids at the security point

When you get to the TSA checkpoint, hopefully after not too long a wait, you must remove the quart-sized resealable bag containing your liquids from your carry on and place it separately in a tray to go through the x-ray machines.

Please do not leave them in your carry on bag; otherwise, you will be delayed and have to put them through again.

This is the official Transportation Security Administration video explaining the 311 liquids rule and the maximum liquid permitted in carry on bags in an airplane:

What is considered a liquid for airport security?

I think the 311 liquid rule is pretty clear.

Now, what is and is not considered a liquid is rather less straightforward, so I will try to give as complete a description as possible and then answer some of the most often-asked questions.

The easy answer is that almost anything that isn’t solid is considered a liquid, such as liquids, gels, and aerosols.

These include:

  • Liquids – pretty obvious, really but they include shampoos , hair conditioners, liquid soaps, bottled water and cans of soda
  • Aerosols – such as deodorant , body sprays etc
  • Gels – shaving gel, gel lip balm
  • Creams – face and hand creams, skincare, shaving cream, suncream , moisturizer and toothpaste
  • Powders (even these can be considered a liquid)

You can buy many of these in travel-size containers.

Some types of makeup are pretty obviously liquids, but just to be clear, the following is considered a liquid, so it is subject to the restrictions and rules detailed above.

  • Nail polish
  • Nail polish remover
  • Tube mascara
  • Liquid, cream or gel eye shadow
  • Gel lip balms
  • Liquid foundation (powdered is fine proved it is less than 12oz)

Are there any exemptions to the liquid rule?

There are some exemptions to the 3-1-1 liquids rule. These exceptions mean they can be in containers larger than 3.4 ounces, and they do not have to go in the quart-sized plastic bag, although they do need to be placed in a separate bin for additional screening.

Read my post for full details: What liquids do not go in a liquids bag?

Liquid medication

It is possible to carry medically necessary liquids larger than 3.4 ounces to treat certain medical conditions. These include saline solution used to clean contact lenses , lotions, liquid antibiotics, etc.

It doesn’t matter if the liquid is in a bottle, an aerosol, a cream or in gel form.

The full updated details are best read on the TSA website – Disabilities and Medical Conditions

Baby and infant products

maximum liquid on plane for baby

There are exceptions if you are traveling with a baby or infant, but you must have the baby with you, which may sound rather obvious but means you cannot carry it for someone else. Breast milk can be carried without a baby, though.

You can take “food” items for the baby in reasonable quantities through airport security that exceed the 3.4 ounces/100ml rule, such as:

  • made-up baby formula
  • expressed breast milk
  • sterilized water to make up baby formula (must be in a baby bottle)

You should tell the TSA officer that you have these before you put them through the x-ray machine for additional screening.

You can read my more detailed article about flying with a baby or toddler

You are allowed to carry duty-free liquids provided they are in unopened, secure, tamper-evident bags (as supplied by the duty-free store) if more than 3.4 oz or 100 ml in your carry-on bag and also if the following is true:

  • The duty-free liquids were purchased internationally, and you are traveling back to the USA with a connecting flight.
  • The liquids are packed in a transparent, secure, tamper-evident bag by the duty-free store, and they have not been tampered with or opened when shown at airport security.
  • You have the original receipt for the liquids.
  • The purchase was made within the previous 48 hours.
  • The items in their bags should be removed from your carry-on and screened separately.

Liquids you cannot take in carry on

Several liquids cannot be carried in hand luggage. Most of these are flammable or hazardous.

These include :

  • cooking fuel
  • lighter fuel
  • pepper spray and other self-defense sprays
  • liquid bleach

Airline liquid rules

Don’t forget that these limits do not refer to the maximum amount of liquid allowed on a plane but the maximum allowed to be taken through airport security.

Airline liquid rules allow any liquids that are permitted through airport security. Plus, once you are through the TSA checkpoint, you can purchase any reasonable amount of liquids from any stores in the departure lounge and take these on the aircraft with you.

You can also fill water bottles from a water fountain or buy bottled water.

Useful tips for carrying liquids in carry on

These days, particularly with budget airlines, it costs extra to take checked bags so many passengers opt to travel with only carry on , particularly if it is a relatively short trip.

This can present a problem with many personal hygiene products, such as shampoo, conditioners, face creams etc as they generally come in bottles that are too large to go through airport security.

So you either have to:

  • find your favorite brands in bottles small enough to go through security (which often isn’t possible)
  • try and buy some larger bottles when you arrive at your destination. But that may prove not so easy, particularly if traveling overseas. Even if you can, it also means you are likely to throw away much of what you have bought before you return as you can’t take it with you due to the liquids rules, which is a waste.

The solution is to buy some refillable bottles that meet the liquid rules and fill them up from your larger containers before you leave home.

These are some that I have used that also come with a TSA approved quart-sized bag and a folding toothbrush .

The TSA liquid rules state that liquids must be in containers no larger than 3.4oz/100ml each to be taken through airport security. All the liquids must fit into one quart-sized resealable plastic bag. Only one plastic bag containing liquids is allowed per passenger in carry on.

Liquid limits in carry on could be scrapped once 3D scanners fully operate at airports.

How many Ziploc bags can I take on a plane?

Only one ziplock liquid bag containing liquid items may be taken through airport security per passenger.

Can you bring multiple 3 oz bottles on a plane?

Yes, you can take as many 3.4-ounce bottles containing a liquid on a plane as you can fit in a quart-sized liquids bag.

Are makeup wipes considered a liquid?

Makeup wipes, baby wipes, and sanitizer wipes are all allowed on a plane as they are not treated as a liquid.

Is toothpaste considered a liquid?

Toothpaste is considered a gel or cream and so for airport security is treated in the same way as a liquid. This means that you can take a small travel tube that is less than 3.4 ounces, and it must go in a quart-sized liquid bag.

Is deodorant a liquid for air travel?

Deodorants are treated as liquids on a plane unless they are solid “stick” deodorants, so any others must be 3.4 ounces (100 milliliters) or less.

The Airline Liquid Limit You Need To Know Before Flying

Last Updated on December 4, 2021

Your airline should inform you about the liquid limits for flying or they will be published somewhere on your airline’s website.

But it’s not your airline that sets the rules or enforces them.

It doesn’t matter if your airline is Alaska, Allegiant, American Airlines, Delta, Frontier, Hawaiian, JetBlue, Southwest, or Spirit. All airlines have the same liquid allowance because the liquid regulations are set by the Federal Aviation Authority (FAA) and enforced at the airport by the Transportation Security Administration (TSA).

There are actually three limits that you need to know about before flying.

Let’s take a look at them now.

TSA / Airline Carry On Rules

Your carry-on bag will be inspected at the airport security checkpoint by the TSA and they will make sure you are not exceeding the liquid allowance. Your airline won’t look inside your luggage at all.

Limit A – Travel Size Containers

The first airline liquid limit is that you must pack liquids in travel sized containers. Travel sized means bottles or containers that are 3.4 ounces or less .

If 3.4 oz strikes you as a strange amount to choose it’s because that it’s equivalent to 100 ml.

It’s the size of the container that is important, not the amount of liquid remaining in the container. So you can’t bring a 5 oz bottle when there is only 3 oz remaining inside.

Refillable travel size containers are a great money saving purchase because you can just fill them up from the big bottle you have at home. Buying travel size versions of products is expensive.

I like to use a collection of bottles and containers of different sizes. There is no sense in packing 3.4 oz of liquid if you only need 1 oz for your trip. A kit like this would be perfect:

air travel max liquid size

The TSA considers liquids, gels, aerosols, pastes, and anything that you can smear or spread to be a liquid.

My favourite example of this is peanut butter . Peanuts are treated as a solid, but peanut butter is considered a liquid by the TSA.

Limit B – All Containers Must Fit Inside A Quart Size Bag

The second airline liquid limit is that all your travel size liquids must be packed in a one quart size bag .

You can buy a reusable ‘ TSA Approved Toiletry Bag ’ that isn’t actually TSA sanctioned but will work anyway. Or you can use a simple resealable bag like a Ziploc plastic baggie that has the capacity of 1 quart .

You might be able to fit 6 or 7 travel size bottles in a quart size bag. If you buy a reusable one then you’ll probably fit more since they are not actually quart-sized but you’ll probably get away with it.

Limit C – Only One Bag Per Passenger

The third airline liquid limit is that you are only permitted one plastic bag per passenger . You can’t bring two liquids bags if you are bringing two suitcases. It’s 1 bag each maximum.

There is no way around the one bag rule. If you are struggling to fit all the liquids you need in one bag the best way to deal with that is to try to substitute solid versions of products.

For example, a solid bar of soap can replace shower gel.

A solid stick deodorant can replace an aerosol spray.

You can even buy solid toothpaste tablets that might suffice until you are able to visit a local shop.

My top tip is that the TSA doesn’t consider wet wipes to be a liquid .

So if your liquid product is available in a wet wipe form then the wipes will make a great substitute and free up space in your liquids bag. Makeup cleansing wipes are a good example.

These three airline liquid rules are called the 3-1-1 by the TSA:

  • 3 .4 oz containers
  • 1 quart sized bag
  • 1 bag per person

There also a 4th restriction about the type of liquids you can pack. Let’s call it Limit D.

Limit D – No Flammable Liquids Unless They Are Toiletries

You can’t bring flammable liquids or hazmat liquids even in containers smaller than 3.4 oz unless they are toiletries.

My favourite example of this is that you can bring bug repellant that you apply to your skin, but you can’t pack an aerosol bug killer spray even if it’s under 3.4 oz because it’s flammable and not a toiletry.

The TSA defines a toiletry as something that you use on your skin.

Exceptions To The Airline Liquid Limit

The liquid limit that your airline talks about is only for getting past the TSA security checkpoint.

It’s not a limit to how much liquid you can bring on the plane, it’s a limit to how much liquid can be in your carry-on bags when you go through the screening process at airport security.

That means that if you buy any liquids after the security checkpoint then you can bring them on the plane no matter what size they are. So you can fill up your water bottle after the TSA checkpoints.

There are also a few cases where you can bring containers larger than the 3.4 oz regulations normally permit.

  • You can bring breast milk, juice, liquid foods, or drinks for infants in reasonable quantities
  • On international flights you can carry duty free liquids in a secure tamper evident bag
  • You can bring medically necessary liquids in containers larger than 3.4 oz and you don’t need a doctors note.

If you have a container of liquid that is larger than 3.4 ounces and you think it qualifies for an exemption then feel free to place it in a separate bin at the x-ray machine for additional screening.

Airline Checked Baggage Liquid Limits

Liquids are not limited in checked bags as strictly as they are in carry-on luggage.

Only Limit D from above applies. You cannot pack flammable or hazmat liquids in checked bags because of the fire risk.

You can pack as much beer or low strength wine as you like but you can only pack 5 litres of alcohol that is between 24% and 70% ABV. Alcohol over 70% ABV is prohibited because it’s too flammable.

Lastly any toiletry aerosols that you pack in checked luggage should be in containers smaller than 18 oz and you are only allowed to pack 70 oz per person of toiletry aerosols in checked luggage.

The Bottom Line

The liquids rule that your airline talks about is actually the FAA carry-on liquids rule that will be enforced by the TSA at the airport.

There are 3 limits or restrictions. Containers can be 3.4 oz maximum . They all need to go in a one quart size bag . And you can only bring one liquids bag per person.

There are exceptions to the regulations for medically necessary liquids or liquids for babies and infants.

Taking Liquids in Airplanes: How, How Much, and How to Do It

Travelpro Travel Expert Editor

Tips & Tricks

Taking Liquids in Airplanes: How, How Much, and How to Do It

The TSA fluid limit for carry-on luggage exists for a reason. In 2006, Briain, the U.S., and Pakistan security foiled a plot by al-Qaeda operatives to set off bombs on airplanes using liquid explosives. The plan was to smuggle bomb materials onto planes using plastic drink bottles. Since then, the TSA has limited the amount of liquid passengers can bring onto planes to containers no larger than 3.4 ounces, a regulation commonly called the 3-1-1 rule.

The 3-3-1 Rule Simplified

The TSA’s fluid limit rule for carry-on liquids stipulates you can carry no more than 3.4 ounces per container of liquid. 3.4 ounces may seem like an odd amount, but it’s to keep TSA rules consistent with international regulations, which allow for 100 milliliters (3.4 ounces) per container.

The “3” in the 3-1-1 rule refers to the 3.4 ounce limit. All 3.4-ounce containers must fit into a clear one-quart bag: that’s the first “1.” Only one bag is allowed per passenger (that’s the last “1” in 3-1-1). Any liquids that don't meet these limitations cannot go through security and will be thrown away or confiscated.

The TSA and international airport security define substances most people consider to be solids or gasses as liquids, including aerosols, gels, creams, and pastes. Toothpaste, hair spray, peanut butter, shampoo, soup, mascara, and mouthwash are all considered liquids by the TSA. If you can squeeze, spray, or spread a substance, it falls under the 3-1-1 rule.

What are the Exceptions to the TSA Fluid Limit?

The TSA recognizes circumstances may require some passengers to carry more than 3.4 ounces of a liquid in their carry-on bags. Exceptions are made for items you would need during your flight or at your destination, if the items are unavailable at your destination and cannot be purchased after the security checkpoint. In practice, this usually means any of the following items:

  • Baby and toddler drinks and food, including puree pouches
  • Breast milk and infant formula
  • Ice, gel, or freezer packs used to keep breast milk, infant formula, or medically necessary items cool
  • Medical prescriptions that come in liquid, gel, or cream forms

Since 2020 passengers can travel with up to 12 ounces of hand sanitizer, an exception which may change in the future.

Travelers should alert TSA officers to any liquids that are exceptions to the 3-1-1 rule. All medication (liquid or otherwise) should be clearly labeled to help you move through security quickly. The TSA officer may visually check liquid exceptions, send the items through the X-ray machine, or test the liquid’s container for traces of explosives. You are responsible for displaying and repacking 3-1-1 exceptions, so keep any liquids and your  toiletry bag at the top of your carry-on for easy access. Remember that while prescription medication is exempt from the TSA fluid limit, non-prescription medications fall under the 3-1-1 rule.

X-ray screening machines do not affect infant or toddler food or drinks, but some travelers prefer not to take risks. Inform the TSA officer if you do not want food, drinks, formula, or breast milk x-rayed. Security will use other methods to clear the liquid, and you and your carry-on luggage will undergo additional screening. Be aware additional screening will slow your passage through security, so plan for the delay.

Are Frozen Liquids Liquid?

The TSA does not consider completely frozen liquids to be liquid, and therefore not subject to the 3-1-1 rule. The key phrase here is “completely frozen.” If the frozen substance is slushy or partially melted, it must meet the 3-1-1 requirements, regardless of the amount of thawed liquid in the container.

How many liquid ounces can be taken on a plane?

If you're wondering, “how many 3oz bottles can I carry on a plane,” the answer is approximately seven or eight. Any more, and you won’t be able to seal the bag with the containers inside. In terms of how many liquid ounces can be taken on a plane, this translates to approximately 25 liquid ounces.

The Quart-sized Bag, Explained

When it comes to quart-size bag dimensions, the TSA gives you some wiggle room. The average plastic resealable quart-sized bag is 7” by 8”. If you’re packing liquids in a travel toiletry bag, look for one which approximates these dimensions—people have had liquids confiscated for using bags TSA agents felt were too large, whether the bag was full of 3.4-ounce containers or not.

The TSA does not endorse any particular type of quart bag, so you can use anything from a travel toiletry bag to a Ziploc.

Liquids in Checked Luggage

Can you bring full-size bottles in a checked bag? The TSA has more lenient rules about liquids in  checked luggage . You can carry creams, gels, drinks, and toiletry-based aerosols in your checked baggage. 

The TSA prohibits certain liquids that pose a public danger from checked and carry-on luggage. Do not travel with any of the following:

  • Alcoholic Beverages over 70% ABV
  • Aerosols that are not toiletries
  • Flammable liquids
  • Toxic liquids
  • Fertilizer 
  • Insecticide

These liquids are prohibited in any amount, and their discovery during security checks can result in missed flights, arrest, and legal action.

Consider your destination when packing liquids in checked items. In many Islamic countries, for instance, alcohol is illegal or restricted and would be confiscated as you go through customs. Check the laws and regulations of your destination country before flying with liquids internationally.

TSA Increases Hand Sanitizer Allowance for Carry-Ons

'   height=

See recent posts by Airfarewatchdog Staff

If for whatever reason you are flying in the near future, please note that the TSA has updated its carry-on rules for liquids, now allowing passengers to bring up to 12 ounces of hand sanitizer on board.

TSA understands that COVID-19 (Coronavirus) is at the forefront on the minds of travelers, as health officials are encouraging that individuals wash their hands frequently. With that in mind, TSA is allowing one liquid hand sanitizer container up to 12 ounces per passenger in carry-on bags until further notice. Passengers can expect that these containers larger than the standard allowance of 3.4 ounces of liquids permitted through a checkpoint will need to be screened separately, which will add some time to their checkpoint screening experience. Please keep in mind that all other liquids, gels, and aerosols brought to a checkpoint continue to be allowed at the limit of 3.4 ounces or 100 milliliters carried in a one quart-size bag. From TSA.gov

The Centers for Disease Control advises travelers to wash their hands using soap and water, which is still the best way to prevent infection. When hand washing is not an option, hand sanitizers containing at least 60% alcohol may be used. Since this are currently in short supply, you might consider making your own hand sanitizer using alcohol along with aloe gel.

Again, hand sanitizer is the only exception currently made for liquids. It's easy to forget or to even be a little fuzzy on exactly what is and isn't allowed, especially when the rules aren't always consistently enforced across airports. Before you pack up all your lotions and potions for travel, brush up on the TSA's current policies on flying with liquids.

These are the TSA Rules for Traveling with Liquids

  • Liquids, gels, creams, pastes, and aerosols should not exceed 3.4 ounces. You can often find travel-sizes of your favorite products, though it's more economical to just transfer from the full-size version to a smaller size-compliant container.
  • Before you get any wild ideas, that doesn't mean you can cram your carry-on with a bajillion 3.4-ounce bottles of moisturizer. Everything must fit inside a quart-size baggie. You can spend a little on a quart-size zippered number that will last a good while, or make do with a Ziploc. Both work just fine for the TSA.
  • If there's no way you can fit everything you need in a single quart-size bag, the only other option is to pack any extra or full-sized items in your checked baggage.
  • Don't forget, liquid restrictions apply not just to cosmetics and toiletries but also to foods and beverages. That may seem obvious, yet there are stacks upon stacks of confiscated water bottles at the TSA checkpoints on any given day. There are definite grey areas when it comes to what foods and beverages the TSA allows. A full water bottle is an obvious no-no, however, water melon is most certainly allowed. If you're carrying an item you're unsure of, check the TSA's What Can I Bring page.
  • Not a liquid, but often packed alongside them, powders are also something to watch out for when packing. A lesser-known rule enacted by the TSA only a few years ago limits powders to 12 ounces or less. That applies not just to make-up or cosmetic powders but also protein supplements, weight gainers, cooking substances, and anything that would constitute as a powder.
  • Passengers traveling with breast milk, baby formula, or any doctor-prescribed gels, creams, or liquid medications are exempt from these restrictions.

Taking Flight: A Deep Dive into the Maximum Liquid Carry-On Airplane Rule

  • The TSA’s 3-1-1 rule allows a maximum of 3.4 ounces (100 milliliters) of liquids per container in your carry-on.
  • The rule was implemented in 2006 to enhance airplane security against potential threats.
  • Complying with the rule can speed up the security screening process and make your travel experience smoother.
  • Exceptions to the rule exist for medications and certain food items.
  • Being savvy about the rule can save time, money, and stress.

Understanding the 3-1-1 Rule

According to the Transportation Security Administration (TSA), the 3-1-1 rule refers to the maximum amount of liquids , aerosols, and gels passengers can carry in their luggage. It stipulates that each passenger may carry containers with a maximum capacity of 3.4 ounces (100 milliliters) each, all of which should be enclosed in a single, clear, quart-sized plastic bag.

A Quick Trip Down Memory Lane: The Origin of the 3-1-1 Rule

This policy didn’t come out of the blue. The 3-1-1 rule was implemented in 2006 following a foiled terrorist plot that aimed to detonate liquid explosives on transatlantic flights from the United Kingdom to North America . Kip Hawley , former TSA Administrator, underscores the importance of this rule: “The 3-1-1 rule is an important part of our layered approach to security that allows us to separate liquids, aerosols, and gels from other potential threat items and to focus our efforts on items that could be used to cause catastrophic damage to an aircraft.”

Maximize Your Benefits: Tips for Navigating the 3-1-1 Rule

Now that we’ve unveiled the backstory, how can this information help you, dear traveler? Here are some insider tips to keep you savvy about this rule:

  • Be selective about your liquids: Choose multi-purpose toiletries to maximize space.
  • Leverage travel-size versions: They adhere to the TSA regulations and can be a lifesaver.
  • Consider solid alternatives: Swap out your liquid toiletries with solid versions where possible. Solid deodorants, perfumes, and soaps are all game-changers.

Unpacking the Exceptions

Yes, there are exceptions! Medications , infant and child nourishments, and breast milk are exempt from the 3-1-1 rule. However, do inform the TSA officer at the beginning of your screening process about these exceptions.

What is the 3-1-1 rule for carry-on luggage?

The 3-1-1 rule stipulates that each passenger may carry containers with a maximum capacity of 3.4 ounces (100 milliliters) each of liquids, aerosols, and gels in their carry-on luggage, all of which should be enclosed in a single, clear, quart-sized plastic bag.

When was the 3-1-1 rule implemented?

The 3-1-1 rule was implemented in 2006 following a foiled terrorist plot that aimed to detonate liquid explosives on transatlantic flights.

What are some tips for navigating the 3-1-1 rule?

Being selective about your liquids, leveraging travel-size versions of your favorite products, and considering solid alternatives for some toiletries are some of the best strategies to comply with the 3-1-1 rule.

Are there any exceptions to the 3-1-1 rule?

Yes, medications, infant and child nourishments, and breast milk are exempt from the 3-1-1 rule. It’s important to inform the TSA officer about these at the beginning of your screening process.

How does understanding the 3-1-1 rule benefit travelers?

Understanding and complying with the 3-1-1 rule can speed up the security screening process, prevent the disposal of personal items at checkpoints, and make the overall travel experience smoother.

Can I carry a separate bag for my medications?

Yes, medications are not subjected to the 3-1-1 rule and can be packed in a separate bag. However, they must be declared and screened separately at the security checkpoint.

Is the 3-1-1 rule only for US airports?

While the 3-1-1 rule was implemented by the US Transportation Security Administration, many international airports have adopted similar measures for security reasons. It’s always wise to check the regulations of the countries you’re traveling to.

Can I purchase larger quantities of liquids after passing security?

Yes, larger quantities of liquids purchased from stores located after the security checkpoint (duty-free shops) or on board the aircraft are allowed. These need to be packed in a secure, tamper-evident bag by the retailer.

Knowledge is indeed power. So now that you’re well-equipped with all the information about the TSA’s 3-1-1 rule, navigating airport security will be a breeze. Keep these tips and tricks in your arsenal, and enjoy a stress-free, comfortable journey. Safe travels!

In Conclusion

Mastering the art of the maximum liquid carry-on airplane rule can significantly streamline your airport security experience. Next time you pack your bags, remember the 3-1-1 rule, and embark on your journey with the confidence of a savvy traveler. So, pack smart, fly high, and make your journey a tale worth sharing.

The U.K. Ended Its Travel-Size Liquid Rule for Carry-Ons—Will the U.S. Do the Same?

By Jessica Puckett

Travelers seamless pattern. People going with luggage. Travel and transportation theme flat vector illustration.

Passing through airport security in the U.K. is about to get easier and more streamlined, as U.K. officials announced that the rule mandating liquids in carry-on bags be 100ml (3.4 ounces) or less will no longer be enforced, starting in June 2024. 

When the rule ends, passengers will be able to carry-on liquids measuring up to two liters in volume, the BBC reports . Additionally, passengers will no longer need to remove electronics from bags, such as laptops. Previously, major airports in the U.K., such as London Heathrow, were known for their stringent enforcements of the liquid rules.

In the U.S., similar policies are still in effect at airports around the country, with the TSA enforcing its so-called “ 3-1-1 ” liquid rule for carry-on bags: all liquids must be 3.4 ounces or less and fit in a single, one-quart clear bag. (Though there are  some exceptions to those rules.)

The more relaxed screening policies in the U.K. are possible thanks to new X-ray scanners that use computed tomography (CT) technology to produce more detailed, 3D images of luggage contents. (The technology is similar to a CT scan you might get at a hospital.) Most airports in the U.K. will need to upgrade their X-ray machines to the newer high-tech versions by June 2024. 

The same enhanced CT technology has been in use at U.S. airports for several years now, with the TSA rapidly expanding the scanners to dozens of airports nationwide. As of May 2022, the agency said it had deployed at least 402 CT units to 163 airports around the country. Over the summer, officials installed more of the scanners at additional airport checkpoints in anticipation of an uptick in air travelers, including at Billings Logan International Airport in Montana , Albany International Airport in New York, Buffalo Niagara International Airport in New York, Cincinnati/Northern Kentucky International Airport and Raleigh-Durham International Airport in North Carolina, the TSA  said in a release . 

With that in mind, will the TSA follow the U.K.’s lead and ditch its rules for carry-on liquids? Currently at U.S. security checkpoints with CT scanners, passengers already have somewhat more relaxed screening rules, as they aren’t required to remove their travel-size liquids, electronics, or food from their carry-on bags, according to the TSA. That was a precursor step to the new U.K. policy at  London City airport , which received CT scanners in November 2022 and announced that passengers no longer had to remove any items from their bags. 

But some industry analysts say scanning equipment is only one piece of the puzzle . “I believe that TSA and other aviation security organizations will study the results from the UK’s decision closely and carefully,” says Henry Harteveldt, an aviation expert and president of Atmosphere Research. “If behavioral profiling and other similar tools allow security organizations to potentially detect people who may pose a danger to airline crews and passengers, it may help reduce the need for measures such as the 100ml limit on liquids and the TSA’s 3-1-1 policy.”

Indeed, it seems U.S. officials plan to take it slow when considering any changes to the current TSA 3.4-oz liquid rule, which has been the international standard since it was implemented in 2006. “Computed Tomography technology produces 3-D images that can be rotated and combined with advanced detection algorithms to produce a substantial improvement in security screening,” Robert Carter Langston, TSA's press secretary, said in an emailed statement. “While we have them deployed at more checkpoints, we are years away from announcing a change to the current liquids rule.” 

Although U.S. passengers still need to pack travel-size liquids for the time being, that doesn’t mean that the security checkpoint hasn’t been seeing other improvements. Aside from rolling out more CT scanners, TSA has been deploying credential authentication technology: new ID scanners that don’t require passengers to show their boarding passes . Earlier in 2022, the agency also began accepting digital IDs from the Apple Wallet app at certain airports and testing an expansion of facial recognition to whisk travelers through even faster.

The new rules on carrying liquids through UK airport security

Air travel is about to get a little easier, with restrictions on liquids relaxed. With some airports struggling to adapt, here's what to expect this summer.

For almost two decades, the queue for airport security has seen travellers hastily gulping down their bottled water and cramming liquid toiletries — limited to 100ml apiece — into a single transparent bag.  

But not for much longer. In 2022, the UK government announced that by June 2024, all major airports in the country would be required by law to install high-tech new security scanners. This would allow airline rules on liquids to be scrapped, among other benefits.

With the promise of speedier queues through departure, it was initially good news. But now, four of the biggest airports — Heathrow, Gatwick, Stansted and Manchester — are on course to miss the deadline, prompting fears of confusion this summer.  

What’s the 100ml rule?

It stipulates that passengers with hand luggage can only take liquids and creams in containers of up to 100ml on board an aircraft. These must be placed in a single, transparent, re-sealable plastic bag, which holds no more than a litre and measures about 20cm x 20cm. The bag must be able to close.

Why was it introduced?

The measures were implemented after a foiled plot by Al-Qaeda in August 2006, during which terrorists attempted to disguise liquid explosives as drinks at Heathrow.  

Why is it changing?

The primary driver is an improvement in security technology. More advanced CT scanners mean that security staff are able to take a more detailed look at passengers’ luggage. As well as negating the need to remove liquids and limit them to 100ml, the new machines mean electronics can stay in bags — without closer inspections —and prohibited items such as weapons and liquid explosives can be better detected. According to Smiths Detection, which makes the scanners, this is thanks to explosives detection algorithms and automated object recognition software.

Why is it taking so long?

Introducing the new machines is a huge financial burden for airports and poses a logistical challenge.“It was always going to be a struggle for the big airports,” a senior aviation source told The Times. “One of the biggest issues they face is fitting the new scanners and retraining staff without impacting the flow of passengers.”

Heathrow, which has 146 security lanes across its terminals, faces the biggest challenge in meeting the deadline, and will have the smallest percentage of new lanes installed come June. A spokesman for Gatwick says it will have made “significant progress” by June but “plans to have completed the operation required to install the remaining scanners in Q1 2025”. Security areas will need to be adjusted at several airports because of the size of the new scanners. The floors in some terminals, especially at Heathrow, need to be reinforced because of their added weight. “The existing scanner is like a washing machine,” says Nick Barton, chief executive of Birmingham Airport. “The new machines are the size of a Ford Transit.”

What impact are the scanners expected to have?

People failing to remove items from their bags or travelling with large bottles of liquids cause delays at airport security, as they result in additional checks. The new machines are expected to cut wait times dramatically, although the fear is that, in the short term, ‘mixed messaging’ will lead to delays — where airports still have both old and new technology, passengers won’t know what to expect. At London City, which has already completed the upgrade, the average time it takes to conduct security checks is now only three minutes and 45 seconds, down from seven minutes in 2022.  

What will happen this summer, and what’s next?

Discussions are ongoing. Heathrow, Gatwick, Stansted and Manchester are expected to be given an extension until 2025, meaning passengers at these airports will be told to follow existing rules — even though some lanes will have been upgraded — to avoid queues. Other airports are understood to be on course, and passengers will benefit this summer. Along with London City, Teesside Airport has already scrapped the 100ml rule. This change will only affect departures from the UK — arrivals into the country will still have to follow the rules of their outbound airport.

This forms part of a raft of new technologies being introduced over the next decade. Facial recognition and AI are playing a big role: in the future, passengers will board planes without showing documents — faces will be automatically matched to passports. Border Force has also started a process to see e-passport gates replaced with ones that do not require them to be inserted.  

Is the change also happening in the US or elsewhere?  

There are other countries that are looking at amending the rules on liquids in light of the new technology, although the UK is among the first to make a blanket change. Spain is on course to follow suit by 2026, thanks to a phased installation of the new scanners. Some other transport hubs, such as Amsterdam’s Schiphol, Frankfurt and Milan Malpensa, have also installed similar ones, and there are a limited number of lanes at Geneva that passengers can choose to use.

In the US, many airports, such as Atlanta's Hartsfield-Jackson and Chicago's O'Hare, have already installed the new scanners and, in these, the Transportation Security Administration (TSA) has slightly relaxed the rules. Travellers here are generally able to leave their food, electronics and liquids in their bags as they pass through — but rules on keeping liquids travel-sized remain, permitting just 3.4 ounces (100ml) or less in a single one-quart transparent bag. A nationwide rule change is still expected to take some time, due to the sheer number of airports across the country. On the whole, travellers can expect to encounter legacy rules at some point on their travels over the coming years.
