TSA Weighs Full Water Bottles for PreCheck Passengers at Select Airports

Key points

• TSA is actively considering allowing PreCheck members to bring full water bottles through security at specific airports.
• The change relies on new 3-D CT scanners capable of distinguishing water from other liquids and detecting threats.
• The 3-1-1 liquids rule, in effect since 2006, remains in place for all other travelers.
• TSA officials stated the agency lacks the funding and technology scale to implement this change nationwide.
• The potential rollout is tied to the recent launch of the 'Gateside by TSA' program at 13 airports.

Background

This development follows recent expansions in trusted traveler programs, including the 'Gateside by TSA' initiative launched in September 2026, which allows PreCheck members to access gate areas without a boarding pass at 13 airports. It also aligns with broader post-9/11 security adjustments that have gradually eased certain restrictions, such as allowing shoes to remain on during screening, while maintaining strict liquid controls.

How outlets are covering it

ABC News cited the TSA administrator as the source for the potential rule change, while CBS News credited senior administration officials. USA Today reported that the TSA did not confirm the reports but acknowledged it is exploring opportunities to enhance security and improve the travel experience for trusted travelers. All outlets agree that the change is limited to PreCheck travelers and specific airports, with no nationwide implementation planned due to funding and technology constraints.

Why it matters

This potential change could significantly improve the convenience for frequent travelers who use TSA PreCheck, eliminating the need to empty or discard water bottles at security checkpoints. It also highlights the ongoing evolution of airport security technology and the agency's efforts to balance security with passenger experience for vetted individuals.

What to watch

The TSA will evaluate the operational effects of the current 'Gateside by TSA' rollout before expanding it. Any changes to screening policies, including the potential water bottle exemption, will be announced through official channels. The agency has not provided a timeline for the implementation of the water bottle rule.
