39 airports · 0 with a recorded check · 0 with source guidance only · 39 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. 0 of 39 airports in United States have a recorded source check or editor approval; 0 more have source guidance without a recorded check. The rest default to the conservative 100ml baseline.
What to do: Pack to the stricter rule on a return trip — the airport you fly home from sets the limit, not the airline.

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.
