TSA could soon ease liquid rules as checkpoint changes expand

The familiar airport routine of tossing water bottles and removing shoes may soon be a thing of the past. Homeland Security Secretary Kristi Noem says the Transportation Security Administration (TSA) is reassessing long-standing checkpoint rules in an effort to streamline the process without compromising safety.

At a press conference in Nashville July 16, Noem said she’s “questioning everything TSA does,” suggesting that updated technology could render certain security measures unnecessary. Her comments come amid historic travel surges and recent announcements from TSA on new screening procedures.

The 3.4-Ounce Liquid Limit May Be on the Way Out

One of the most well-known TSA rules—the restriction on carrying liquids over 3.4 ounces—could soon be lifted. The limit, in place since 2006, was enacted after authorities stopped a terrorist plot involving liquid explosives on flights.

But that rule could be lifted soon.

“We have put in place in TSA a multilayered screening process that allows us to change some of how we do security and screening so it's still as safe,” Noem said.

Former TSA Administrator John Pistole told CBS News that newly installed computed tomography (CT) scanners are a game changer. These 3D-imaging machines automatically detect explosives and other threats, offering a clearer picture of bag contents than traditional X-rays.

Shoes May Stay On in the Near Future

Nearly a week prior, on July 8, TSA announced it will begin allowing passengers to keep their shoes on at certain checkpoints—another sign that the agency is shifting away from long-standing practices.

Noem shared her vision during the Nashville event: “My goal would be that someday, somebody would be able to walk into an airport, walk through a scanner and go right to their airplane.”

Why Now? Travel Hits Record Highs

TSA reports that 8 of the 10 busiest travel days in U.S. history have happened in 2025. With more travelers than ever and evolving threats, the agency appears ready to modernize.

Security officials say maintaining safety while improving efficiency is the goal—and that new technology is making it possible.

What’s Next for Air Travel Security?

Though the changes are rolling out gradually, travelers should expect more updates in the months ahead.

For now, TSA recommends checking its official website for current rules, especially before heading to the airport during peak travel seasons.
