Can I bring a sealed bottle of water through TSA?

So you can't bring H20 or any other liquids more than 3.4 oz. (well there are some exceptions) through security, but you CAN bring an empty bottle. Just fill it up on your way to boarding your flight after screening.



No, you cannot bring a full, sealed bottle of water through a standard TSA checkpoint in 2026, as it violates the 3-1-1 liquids rule (3.4 oz or 100ml limit). Even if the seal is intact, security officers will require you to either drink it or discard it before screening. The only way to bring a full water bottle through security is if it is for a medically necessary reason or contains baby formula/breast milk, both of which must be declared and screened separately. A popular travel "hack" is to bring a completely empty reusable bottle through security and fill it at one of the filtered water stations or fountains located inside the secure terminal area. This ensures you have water for your flight while staying fully compliant with federal liquid regulations.
