The Transportation Security Administration is considering allowing TSA PreCheck travelers to pass through security checkpoints at select airports with full water bottles, leveraging advanced CT screening technology to automatically distinguish water from other potential threats as part of a potential upcoming program change.
Travelers accustomed to hastily finishing their beverages at airport checkpoints could soon see a major shift in how they navigate security lines. Senior administration officials revealed to CBS News on Wednesday that the agency is actively evaluating a policy adjustment aimed at trusted travelers, though the potential update remains under consideration for the coming months.
Advanced CT Screening Technology Drives the Potential Shift
The operational foundation for carrying large water bottles through security relies entirely on hardware capabilities. The proposed changes would initially deploy only at a select number of airports equipped with advanced CT screening technology and automated detection capabilities. These modern machines possess the precision required to distinguish water from other liquids and identify potential security threats without requiring passengers to empty their containers.
Will full water bottles finally be allowed through airport
Despite the technological capability, broader implementation faces severe structural limitations. While the technology to scan full bottles of liquid exists, the agency has not yet acquired the necessary scanning hardware at the scale required for nationwide deployment, even just for PreCheck users, primarily because funding for such an extensive rollout is currently unavailable.
The 3-1-1 Rule and Liquid Restrictions Remain Fully in Effect
For all other passengers and airports, standard restrictions are locked in place. The agency is not presently prepared to eliminate limits on all liquids, meaning the familiar rules governing carry-on luggage continue to apply across the aviation network.
The enduring framework requires that carry-on liquids generally must be in containers of 3.4 ounces or less. Large water bottles have historically remained restricted because legacy security scanners cannot reliably detect the difference between water and harmful liquids.

Broader PreCheck Expansion and Security Lane Modernization
This discussion regarding full water bottles coincides with other adjustments across the agency’s expedited screening networks. The agency recently launched its Gateside by TSA program for eligible members. This initiative allows approved PreCheck members without airline tickets to pass through security and enter gate areas.
The gateside initiative initially operates at 13 airports and is expected to expand after the agency evaluates passenger volumes and operational effects of the initial rollout. Meanwhile, separate modernization efforts are underway to streamline passenger processing. According to ThePrint, the agency is planning to roll out PreCheck lanes at some airports soon featuring e-gates with facial comparison technology, so flyers do not have to worry about their boarding passes and IDs, aiming to simplify and speed up the checking process.
Understanding the Financial and Operational Scope of PreCheck
Why Are US Airports Allowing Water Bottles After 25
PreCheck serves as a program run by the U.S. government that allows travelers to bypass standard security lines and instead undergo an expedited screening process. Membership costs $85 or less for five years, depending on which authorized enrollment provider travelers use.
Before gaining approval, travelers undergo a security check before being approved. Once cleared, members typically experience a streamlined screening process that the agency states normally takes 10 minutes.
Logistics and Unresolved Timeline Questions
While the prospect of carrying water through checkpoints marks a potential departure from rules established in the wake of stricter airport security following the 9/11 terror attack—coming ahead of the 25th anniversary of the event—exact operational details remain fluid. Senior administration officials did not say what specific airports may be included in the new program.
As the agency continues to evaluate operations and infrastructure, travelers eyeing relief from liquid restrictions will need to monitor how quickly advanced CT scanners can be integrated into broader airport infrastructure beyond limited trial locations.
