What Counts as Liquid on a Plane? | BudgetAir.com Blog (2024)

When you pack a suitcase or travel bag before a flight, it is quite common to feel a little confused as to what you are allowed to bring onto the plane, especially when it comes to liquids. The Transport Security Administration has created some important guidelines on what is considered a liquid, and what travelers are allowed to bring in their bags.

Often, passengers who travel less frequently or haven't traveled in a long time find themselves questioning whether they will be allowed to pass through security with common items such as makeup, toothpaste, and contact lens solution. Security officers do not enjoy telling passengers that a certain amount of liquid can't go through a checkpoint, so it is also important to know the volume of liquid that is allowed through.

With so much confusion, BudgetAir.com has provided a guide on what is considered a liquid and what you can do to make sure that you clear security quickly and comfortably with your packed bags.

What the TSA considers liquid on a plane

There are a few restrictions on the quantity and packaging of items in your hand luggage. To ensure that you have a smooth ride through security, it is important to know which liquids you can pack in your hand baggage. According to TSA guidelines, any substance that is free-flowing or viscous is considered a liquid, including liquids, aerosols, pastes, creams, and gels.

So is mascara considered a liquid?

Yes, when it comes to makeup, the following items are considered liquid cosmetics:

  • mascara
  • nail polish
  • perfume
  • moisturizers
  • concealer
  • eyeliner
  • foundation

What is the 3-1-1 liquids rule?

Travelers are only allowed liquids in bottles with a volume of 3.4 oz (100ml) or under in their hand baggage. These containers should be packed in a durable, zip-top plastic bag. TSA's 3-1-1 rule allows one bag for every passenger. Packing your beauty products in the small, clear bag makes the screening process easy.

Packing tips for your beauty products

Use refillable bottles

Using refillable bottles or containers is often the best way to transport your beauty products. As per the 3-1-1 rule, travelers looking to take fragrance on the plane should pour the perfume into refillable perfume dispensers instead of packing the entire bottle as it is likely more than 3.4 oz. Don't bring your fragrance in a large container as it will be confiscated. Items like body creams and pastes can also be packed into smaller containers, allowing these to pass through security.

Put your essentials in your carry-on bag

Put your daily essentials in your quart-sized plastic bag to take with you on the plane. It is a good idea to take the items you regularly use, such as mascara, lip balm, lip gloss, hand creams and put them in your carry-on bag. By carrying them with you, you can make sure that you can freshen up after the flight and that if your baggage is lost you still have your essentials at hand.

Opt for a solid makeup and perfume stick

Whenever possible, consider carrying solid makeup. This kind of makeup can easily be packed in hand luggage without the worry of traveling with another liquid. Solid perfume sticks come in smaller travel sizes and allow you to bring your perfume in your hand luggage without worry about container size.

Double-seal your bottles and containers

Double-seal your bottles to avoid any spillage. Wrap the bottles with plastic bags and use tape on any bottle caps and pop-top openings. Pay attention to products such as foundation and mascara as these items can leak easily.

Buy products at the airport

It may seem like a simple idea, but buying your toiletries and liquids at the airport can provide the easiest way to make sure you aren't packing something that doesn't comply with the TSA guidelines. Items including toothpastes, deodorants, shampoo, and perfume can be bought in shops throughout the airport and are sold in handy travel-size containers - perfect for flying.

Even though the 3-1-1 rule of traveling with liquids was passed in 2006, officers still regularly find liquids and aerosols in carry-on baggage. Always remember to put your liquids in travel-size containers of a maximum of 3.4 ounces and pack them in a quart-sized plastic bag. If you are in doubt, pack any liquid over 3.4 oz. in your checked baggage.
