3-1-1 Liquid Rule

Category: travel

A standard security regulation limiting carry-on liquids to containers of 3.4oz (100ml) or less.

All liquid, gel, or aerosol containers must fit inside a single, transparent, quart-sized bag. This limits the quantity of potential explosive chemicals that can be brought into the cabin in liquid form.

Common Examples

• My water bottle exceeded the liquids limit and had to be emptied before we could proceed through the security checkpoint.
• The 3-1-1 liquid rule applies to everything from shampoo and toothpaste to hand sanitizer and perfume containers.
