Can you take empty metal bottles through security?

Yes, you can take a stainless steel water bottle on an airplane. The TSA has no problem with travelers bringing stainless steel water bottles through airport security. The water bottle should be empty and placed in your carry-on bag when you go through the security checkpoint.



Yes, you can absolutely take empty metal water bottles (such as stainless steel Hydro Flasks or Yetis) through airport security checkpoints in 2026. Security agencies like the TSA are not concerned with the container itself, but rather with the liquid inside it. As long as the bottle is completely empty when it passes through the X-ray machine, there are no size restrictions on the container. Once you have cleared security and are in the departures lounge, you can refill your bottle at the many "hydration stations" or water fountains found near the restrooms. This is a highly recommended practice for frequent travelers to stay hydrated during long flights and to reduce the use of single-use plastic cups. Some travelers worry that the metal might trigger the metal detector, but as long as the bottle is placed inside your carry-on bag or a separate bin as instructed by the officers, it will not cause any delays. Just remember to double-check that you haven't left a "hidden" sip of water in the bottom, as even a small amount can trigger a manual bag search.
