Yes, you can take a metal water bottle on a plane. However, there's a crucial condition: it must be empty when you go through airport security.
Explanation
The Transportation Security Administration (TSA) liquid rule restricts passengers from bringing liquids in containers larger than 3.4 ounces (100 milliliters) through security checkpoints. An empty metal water bottle doesn't violate this rule.
Once you've passed through security, you can fill your metal water bottle at a water fountain or purchase a beverage.
Key Points
- Empty at Security: The bottle must be completely empty when passing through airport security.
- Fill After Security: You can fill the bottle once you are past the security checkpoint.
- TSA Liquid Rule: The reason for this is the TSA's 3-1-1 liquids rule.
- Benefit: Bringing an empty reusable bottle is an environmentally friendly and cost-effective way to stay hydrated while traveling.
What Happens if Your Bottle Isn't Empty?
If you attempt to bring a metal water bottle containing liquid through security, you will be asked to empty it. If you refuse, the TSA may confiscate the bottle.
