What is O'Hare Airport's policy on liquid carry-on items?

O'Hare Airport adheres to the Transportation Security Administration (TSA) guidelines regarding liquid carry-on items. These regulations stipulate that liquids, gels, aerosols, creams, and pastes must be contained in containers that are 3.4 ounces (100 milliliters) or less. Additionally, all these containers must be able to fit comfortably inside a single quart-sized, clear, zip-top bag. This policy is designed to enhance security while allowing travelers to bring necessary personal items like toiletries on board.

The focus on the specific size limit and the requirement for a quart-sized bag prevents larger quantities of liquids that may pose a security risk from being brought through the screening process. Understanding this rule is essential for travelers to avoid any delays or confiscation of their items during airport security checks.
