The 3-1-1 rule refers to the regulations set by airport security for carry-on liquids, gels, and aerosols.
Understanding the 3-1-1 Rule
The 3-1-1 rule is a guideline established to streamline airport security checks regarding liquids, gels, and aerosols in carry-on baggage. Here's a breakdown:
- 3.4 ounces (100 milliliters): Each liquid, gel, or aerosol must be in a travel-sized container that is no larger than 3.4 ounces or 100 milliliters.
- 1 Quart-sized bag: All of these containers must fit into one, clear, quart-sized plastic bag.
- 1 Bag per passenger: Each passenger is limited to only one quart-sized bag.
In summary, each passenger is allowed to bring travel-sized containers that are 3.4 ounces (100 milliliters) or smaller of liquids, gels and aerosols, and they must all fit into 1 quart-sized bag with only 1 bag allowed per passenger.
