Currently, liquids are limited to 3.4 ounces per container with exceptions for essential items. Days after announcing that travelers would no longer need to take their shoes off for TSA screening before flights, Homeland Security Secretary Kristi Noem hinted at another possible change.

Current policy allows travelers to bring liquids in 3.4-ounce containers or smaller. Those containers must go in a quart-sized bag. Anything bigger must be put in checked bags. Noem did not give details as to if or when revisions might be made. Last week, the Department of Homeland Security announced plans to end the TSA’s shoes-off policy.

The DHS Secretary is mulling over other changes to the airport security process, including the 3-1-1 liquid rule.

The shoes-off/shoes-on dance at TSA checkpoints will end soon. But there's a catch you need to know about. Here's what we know.
