Airports do not allow liquids over 100ml in carry-on luggage due to security reasons, primarily to prevent the possible transport of liquid explosives or harmful substances. This rule is part of the 3-1-1 liquids rule (3.4 ounces or less per container, 1 quart-sized bag per passenger, 1 bag per item) implemented globally after specific terrorist threats were identified. To avoid inconvenience, pack larger liquids in checked baggage and use travel-sized containers for carry-on essentials, ensuring they fit within the allowed quart-sized bag.

FAQs & Answers

  1. What is the 3-1-1 liquids rule? The 3-1-1 liquids rule limits passengers to carry liquids, gels, and aerosols in containers of 3.4 ounces (100ml) or less, fitting all containers in one quart-sized bag to enhance security.
