Liquid Carry-on Rules: 3-1-1 Guidelines
Air travelers may carry liquids, gels and aerosols in their carry-on bag when going through security checkpoints. The term “3-1-1” refers to three ounce containers, all in a one quart bag, one bag for each traveler.
With certain exceptions for prescription and over-the-counter medicines, baby formula, breast milk, and juice, and other essential liquids, gels, and aerosols, the following rules apply to all liquids, gels, and aerosols passengers want to carry through a security checkpoint:
- All liquids, gels and aerosols must be in three-ounce or smaller containers. Larger containers that are half-full or toothpaste tubes rolled up are not allowed. Each container must be three ounces or smaller.
- All liquids, gels and aerosols must be placed in a single, quart-size, zip-top, clear plastic bag. Gallon size bags or bags that are not zip-top such as fold-over sandwich bags are not allowed. Only a one quart-size, zip-top, clear plastic bag is allowed.
- Each traveler must remove their quart-sized plastic, zip-top bag from their carry-on and place it in a bin or on the conveyor belt for X-ray screening. X-raying separately will allow TSA security officers to more easily examine the declared items. Only one bag per traveler is allowed.
