What are the size restrictions for liquids in carry-on bags?

The Transportation Security Administration (TSA) imposes size restrictions for liquids when carried in hand luggage to enhance security measures. Passengers are allowed to bring liquids, gels, and aerosols in containers that hold no more than 3.4 ounces (100 milliliters) or less per item. These containers must be securely placed in a clear, quart-sized plastic bag. The bag should be easily accessible for separate screening at the security checkpoint. Larger containers, even if partially filled, should be stowed in checked baggage. Exceptions to the 3.4-ounce rule include items like medications, baby formula, and breast milk, as long as they are declared to security officers for inspection. Adhering to these size restrictions helps expedite the screening process, ensuring passenger safety and efficient airport operations.
