U.S. Airports May Soon Abandon 3.4 Ounce Liquid Rule for Carry-On Bags

Thursday, July 17, 2025 by Alex Smith

Flying within the United States might become even more convenient in the near future. Following the recent removal of the requirement to take off shoes at security checkpoints, the Department of Homeland Security is now considering easing another unpopular measure among travelers: the restrictions on liquids in carry-on luggage.

Homeland Security Secretary Kristi Noem told the media that she is "questioning everything the TSA does," referring to the Transportation Security Administration, and hinted at potential significant changes regarding liquid regulations. "I'm questioning the liquids. So that might be the next big announcement on what the liquid amount is," Noem stated.

Although she did not provide specific details or timelines, Noem assured that new layers of screening are being evaluated, which could maintain security without relying on such restrictive measures. "At the TSA, we have implemented a multi-layered review process that allows us to change part of how we conduct security and screening tasks while keeping things safe," she added.

Since 2006, travelers in the U.S. have only been allowed to carry liquids in containers up to 100 milliliters (3.4 ounces) within a resealable plastic bag. This rule was established following the thwarting of a terrorist plot that aimed to use liquid explosives on board planes. Over time, these restrictions have led to confusion and frustration among passengers who have had to discard water bottles, personal hygiene items, and even food products like yogurt or peanut butter.

A Path Towards Streamlined Airport Experiences

The potential relaxation of the liquid rule aligns with an announcement made on July 8 by Noem herself, confirming that passengers would no longer need to remove their shoes when going through security. This regulation was imposed after the failed "shoe bomber" attack attempt in 2001. "Hopefully, the future of an airport, where I want to get to, is that you walk through the door with your carry-on, go through a scanner, and go directly to your plane," Noem explained, envisioning a faster, more efficient, and less invasive process for travelers.

For now, the current regulations remain in place, but Noem's statements suggest a transformation in the American airport experience, driven by technological advancements and a more flexible approach to security.
