Homeland Security Secretary Kristi Noem stated that the agency is considering modifying its liquid restrictions rule for airline carry-ons. This could indicate a significant change in the Transportation and Security Administration’s (TSA) policy, which has been enforced since 2006, serving as a symbol of post-9/11 travel protocols.

Last week, Noem eliminated the shoe-off requirement at TSA security checkpoints in all airports nationwide. She suggested that the 3.4 oz liquids rule might also be rescinded.

“I’m questioning the liquids, so the next major announcement might be regarding the permitted size of your liquids,” Noem remarked at an event in Washington, D.C., on Wednesday, as reported by The Associated Press.

The liquids rule has long been a symbol of post-9/11 security protocols.

The policy has added time at screening checkpoints and made air travel significantly more stressful, as TSA agents check for any containers exceeding the 3.4-ounce limit. Scenes of hurried passengers chugging water or tossing full bottles into trash bins have become routine — and agents are required to confiscate anything that doesn’t comply, often to the frustration of everyday travelers.

The move comes a week after Noem ended the shoe-off requirement, citing newer technology that can scan for potentially dangerous items. She said the TSA wants to keep people safe, but also provide some hospitality as well.

The new changes are being implemented as the U.S. prepares to streamline large events taking place across the country, such as the America250 events, the Olympics and the FIFA World Cup matches.

Noem said Wednesday that she is questioning “everything TSA does” and laid out her vision for airport travel.

“Hopefully, the future of an airport, where I’m looking to go is that you walk in the door with your carry-on suitcase, you walk through a scanner and go right to your plane,” Noem said. “It takes you one minute.”
