So that may be the next big announcement, is what size your liquids need to be,” Noem told a conference in Washington. Will travelers be able to carry bigger bottles? Multiple 1-quart bags of liquids?

"We're looking at our scanners, what we have put in place in TSA, multi-layered screening process that allows us to change some of how we do security and screening so it still is safe." Noem didn't indicate when the updated policy announcement might be made.

Tiny toiletries stuffed into one-quart plastic bags have long been a way of life for frequent flyers who carry their suitcases onboard. That could be the next security screening measure to change, suggests DHS Secretary Kristi Noem.
