Many United Airlines travelers often ask: What exactly is the 3-1-1 rule, and how does it apply when booking a United airline reservation for your next flight?
The 3-1-1 rule is a TSA (Transportation Security Administration) guideline that applies to all airlines operating from U.S. airports, including United Airlines. It requires passengers to pack liquids, gels, and aerosols in containers of 3.4 ounces (100 milliliters) or less, placed in a single quart-sized bag, with one bag allowed per passenger.
If you’re flying with United Airlines, the 3-1-1 rule governs how much liquid you can carry in your hand luggage. Understanding this rule ensures hassle-free security checks and smoother flight booking and travel experiences.

The 3-1-1 rule refers to three simple requirements:
3: Containers must be no larger than 3.4 ounces (100 ml).
1: All containers must fit into one clear quart-sized plastic bag.
1: Each traveler may carry one such bag.
United Airlines adheres to TSA standards, meaning the rule applies to both domestic and international flights departing from the U.S. For travelers booking United airline reservations, this rule helps avoid confusion at security checkpoints.
Passengers can pack items such as toothpaste, shampoo, hand sanitizer, lotion, and other liquid-based items under this rule. Exemptions apply for medications, baby formula, and certain medical supplies, but travelers must declare these at security.
