Yes, you can bring a reusable water bottle, but with a condition regarding its contents when passing through airport security.
According to TSA guidelines, specifically the 3-1-1 Liquid Rule, you cannot bring a reusable water bottle filled with water through security in your carry-on bag. However, you are allowed to bring an empty reusable water bottle. You can then fill it up at a water fountain or filling station after you pass through security.
Here's a breakdown:
-
Before Security:
- Empty reusable water bottles are permitted in your carry-on.
- Filled water bottles are prohibited in your carry-on.
-
After Security:
- You can fill your empty reusable water bottle at a water fountain or bottle filling station.
| Condition | Allowed in Carry-On Before Security? | Allowed in Carry-On After Security? |
|---|---|---|
| Empty Reusable Bottle | Yes | Yes |
| Filled Water Bottle | No | Yes |
Therefore, the key is to ensure your reusable water bottle is empty when going through airport security. You can then conveniently fill it up once you are past the security checkpoint.
