United States airport liquid rules
39 airports · 15 with verified rules · 24 unknown
Pack liquids in containers of 3.4oz (100ml) or less inside a single 1-quart clear bag. This is the TSA 3-1-1 rule and applies at every US airport including JFK, LAX, Chicago O'Hare and Atlanta.
Rule basis: TSA enforces the 3-1-1 rule (3.4oz per container, 1 quart-sized bag, 1 bag per passenger) at every commercial US airport. No US airport is separately verified as allowing above-100ml cabin liquids.
What to do: Pack to the stricter rule on a return trip — the airport you fly home from sets the limit, not the airline.
Liquid Limits is a travel planning tool, not an official aviation source. Always confirm with the airport before you travel.
Traveller warning: the airport you depart from sets the rule, not the airline. On a return flight you'll face the rule at the airport you fly home from — which may be stricter than your outbound airport.
