Airport Security Rules For Taking Liquids On A Flight 


Regardless of your situation, the 3-1-1 rule is a must-know when it comes to airport security. This rule explains how to get through security in a hurry, and it can help avoid getting caught with multiple bags.

Getting caught up in a security line is one of the most frustrating parts of traveling. Usually, you end up surrendering anything that you were supposed to bring with you.

Each passenger is permitted to bring one quart-sized bag of liquid products through security. This includes shampoo, toothpaste, gel, and aerosols, as well as hair products and perfumes. The products should be stored in travel-sized containers or reusable bottles.

If the contents of your bottle are larger than 3.4 ounces, you can’t bring them through security. You can however bring a reusable bottle with you if it’s empty when you pass the checkpoint.

Having the ability to store all of your liquids in one bag is also beneficial, as they can be easily removed for security screening.

Liquid Exceptions At The Airport 

Typically, the 3-1-1 rule applies to carrying liquid items on a flight. However, there are some exceptions due to COVID-19 and other health issues. For instance, you can take more than 3.4 ounces of hand sanitizers and specific necessary medications.

Due to the SARS pandemic, the TSA is allowing carry-on bags to carry 12 oz of hand sanitizer.

The TSA also allows travelers to carry medication through security, as long as they bring the proper liquids with them. This includes liquids that are medically necessary to keep your medication cold.

Although the 3-1-1 rule does not apply to breast milk and baby formula, you should still bring these items with you in order to keep them cool. You do not need to bring a child to carry these items with you.

The 3-1-1 rule also applies to certain food items, such as peanut butter and yogurt. However, these items must be packed in their resealable bags.

Carrying Powders On A Flight 

The airport regulations do not prohibit you from taking powders in your carry-on. There are no amount limitations as the 3-1-1 rule does not apply to this item. However, you may experience additional security checks for taking more than 12 oz powder.

Although powders and other substances that are similar to powders are not restricted in carry-on bags, they will require additional screening if they contain more than 12 ounces.

Items You Cannot Take On A Flight 

The TSA does not allow you to bring razors with blades in your carry-on luggage. You can also not take more than 3.4 ounces of alcohol nips. Besides that, flammable substances such as lighter fluids are also not allowed on a flight.

Some items that can’t be brought into carry-on bags include knives, fireworks, and lighter fluid. However, some of these items are obvious, such as a foam toy sword or a Magic 8 Ball.

You can still bring certain items through security, such as knitting needles, scissors, and screwdrivers. The TSA has a list of prohibited items that can be found on its website.

Things You Need To Board A Flight 

As per the new regulations, you cannot fly without an authentic ID, such as a government-issued ID or military ID. All adults will have to show the document to get on the flight. You also have to present your boarding pass for flying.

Starting October 1, 2021, you will need to have a Real ID in order to fly. This deadline was pushed back due to the outbreak of the coronavirus.

Not having valid identification is one of the most frustrating parts of traveling. All adult passengers 18 and older must have a valid ID to pass through the airport security.

During the SARS emergency, the TSA allowed travelers to use expired driver’s licenses. These IDs must have been issued after March 1, 2020.

Rules For Carrying Full-Sized Sunscreen On A Flight 

Sunscreens fall under the liquid category as per the TSA. This means you cannot carry a full-sized item on a flight. Instead, you have to follow the 3-1-1 rule and ensure that you don’t bring more than 3.4 ounces of sunscreen.

One of the most confusing items about the security system is the 3-1-1 liquids rule. This rule, which was created by the TSA in 2014, is usually used to determine which items can be carried through security.

On Sunday, the TSA announced that sunscreens would be allowed in carry-on bags and through the checkpoints. However, the agency clarified that you cannot bring sunscreens over 3.4 ounces.

The 3-1-1 rule allows travelers to carry aerosols, gel, and liquid products into planes. However, these items must not contain more than 3.4 ounces. If they do, they should be placed in a 1-quart resealable bag.

The 3-1-1 rule also states that all liquids must be in a 3.4-ounce container or less. In addition, all bags must have the 1-quart capacity.

If the container holds more than 3.4 ounces, it’s required to be placed in the checked bag. During the SARS situation, the agency allowed a 12 oz container of hand sanitizer to be brought in.

On its website, the TSA states that it allows carry-on bags containing medically necessary liquids and aerosols. However, these items must be declared to the security officers at the checkpoint.

Despite the agency’s announcement, there has been a lobbying effort by the dermatologists at Brown University to allow sunscreens to be carried on.

The agency also allows travelers to bring in various food items that are in a container that’s less than 3.4 ounces. Some of these include dairy products, juice, peanut butter, and salad dressing.

The TSA allows you to bring liquid and solid medications on a flight after the screening. You can also carry more than 3.4 ounces of such drugs by getting a doctor’s letter. Equipment such as syringes, pumps, and IV bags are also allowed.

You can bring liquid or solid medications through security, as long as they’re screened. You can also bring in pill or solid form.

The following elements are also permitted:

  • Breast milk and infant formula are both good options.
  • Water, juice, or “liquid nourishment” like Boost are among the liquids and gels required for a traveler with a medical condition.
  • Ice packs, freezer packs, IV bags, pumps, and syringes are examples of medication-related accessories.
  • Products containing gel or liquid, such as mastectomy products and various cosmetic or medical enhancement items

Make sure that the medication’s label is clearly indicated. Although the Transportation Security Administration doesn’t require travelers to carry medication bottles, states have their own regulations.

The TSA doesn’t require travelers to bring their medication with them in order to notify an officer if it’s in liquid form.

Tips To Avoid Losing Your Liquids At The Security Section 

Typically, the airport security will confiscate your liquids if you don’t follow the guidelines. You must pack the relevant drink in a quart-sized bag in your carry-on. You should also avoid taking more than 3.4 ounces unless you have a special permit.

If you’re feeling nervous or crying, it can be spotted by airport behavior detection agents. They use their training to detect unusual gestures. They usually apprehend drug smugglers and those who are carrying banned items.

Since snakes and other animals are not allowed to enter carry-ons, avoid hiding them in your bag. An officer even found a live snake inside a pillowcase.

Due to the number of guns found in checked bags, Parker said that they usually confiscate about 20 handguns a week. He also mentioned that passengers should check with their travel agents to see if firearms are allowed in checked baggage.

Although it’s fine to bring a few ice packs with you, the containers should be screened to make sure they’re safe. The TSA also suggests that travelers only bring what they need in reasonable quantities.

Baby Food

If your kid will most likely consume more than 3.4 ounces of food during the flight, then bring more than 3.4 ounces in his or her carry-on bag. The agency also suggests bringing homemade containers or jars. Remember, if it’s an emergency, bring it in before the security check.

Packed Bottles Of Water 

Typically, you cannot carry bottled water on a flight. However, you may be allowed to bring the liquids if you’re traveling with kids. The best part is that you can take multiple bottles of more than 3.4 ounces in such a case. 

Although it’s technically illegal to bring bottled water on an airplane, traveling with children can be allowed, according to What to Expect. This means that you can bring multiple bottles of water in your carry-on luggage.

Liquid Medications And Accessories

The agency will never take away medication, even if it’s in its carry-on. However, if you’re bringing a liquid form of medication, make sure to bring in the appropriate amount of liquids.

Large Wipes For Disinfecting 

Wipes are not liquids, but they still used to fall under the 3-1-1 rule and amount restrictions. However, the guidelines have changed because of COVID-19. Now you can bring big alcohol and disinfectant wipes in multiple containers in your carry-on.

You can also pack multiple wipes into your carry-on bag to wipe down every inch of the plane. The new pandemic rules also allow the use of individually packaged alcohol wipes or jumbo containers of hand wipes.

Items In The STEBs

Bras With Gel Filling 

Nowadays, bras with gel filling have become famous for helping small-sized women stay comfortable. Typically, gel items come under the 3-1-1 liquid rule. However, you can carry bras larger than 3.4 ounces by going through additional security checks before boarding.

Although they’re not designed to be used on airplanes, gel-filled bra helpers can be discreetly placed through security checks. If they’re larger than 3.4 ounces, they may require additional screening. However, there are some things to be aware of when it comes to security.

Liquid Or Spray Hand Sanitizers 

Hand sanitizers used to fall under the 3.4 ounces rule a few years ago. However, the airport security has increased the quantity to 12 ounces because of the pandemic. This rise is mainly because most bottles are more than 3.4 ounces.

In April, the agency allowed carry-on bags to carry 12 ounces of hand sanitizer, since many bottles exceed the 3.4-ounce limit. However, be aware that this new rule applies to all types of hand sanitizers. Also, make sure to check the safety label before going through security.

Saline Or Other Medicinal Solutions 

Typically, the saline solution must be in a container of 3.4 ounces container. However, you can exceed the quantity if you require more liquid. In that case, you should inform the airline beforehand and pack the item in a quart-sized transparent bag.

Ideally, you should place your contact solution in a 3.4-ounce container. However, if you need to take it more than that, then place it in a quart-sized plastic bag.

Medicine Such As Cough Syrups 

The pandemic has caused a lot of medicine guidelines to change. This is why you can carry more than 3.4 ounces of cough syrup on the plane. However, you must pack the medicine appropriately and take it only in your carry-on bag.
