Can I bring a full water bottle through security?

Concerns & risks

You were trying to stay hydrated on your trip, but you weren't sure if you can bring water through security.

Airport water is expensive.

Causes & evidence

Liquids over 3.4 oz aren't allowed through security; bring an empty bottle. See TSA liquids rule.

What to do

1. Empty it before security.
2. Refill after.

Common mistakes: Common mistakes: bringing a full water bottle to the checkpoint. Bring an empty one and fill it after security at a water fountain or bottle station. Check that your bottle is easy to clean. Empty bottles of any size are fine to carry through. Bring one that clips to your bag so it's easy to carry. Some airports have filtered water stations after security. If you forget and bring a full bottle, you'll likely be asked to empty it or toss it, so drink it before reaching the checkpoint. Frozen liquids may be allowed if they are completely frozen solid at screening, but check TSA's rules. Staying hydrated helps you feel better after a long flight, especially in dry cabin air.

Speed Man tip: Many airports have refill stations.

Wrap-up: Empty. Refill. Save money.
