Liquids in your JetBlue cabin bag: the 100ml rule
The liquid limit is set by the airport you go through security at, not by JetBlue. At most airports each container in your hand luggage must be 100ml or less; 12 of the 63 airports we track allow up to 2 litres, and some apply different limits at different checkpoints.
The rules for carrying liquids in your hand luggage depend on the airport.
At most airports, you cannot take liquids in containers larger than 100ml through security. This still applies if the container is only part full.
