• 3.4 ounces (100 milliliters) is the maximum size for each liquid container.
• All containers must fit into a single, clear, quart-sized zip-top bag.
• Each passenger is allowed only one quart-sized bag.

This rule applies to all liquids, gels, and aerosols, including beverages, creams, and lotions, which means planning ahead is crucial for a smooth airport experience.
