Yes, you can bring a bottle of water on a plane, but with restrictions.
Liquids Through Security
You cannot bring a bottle of water filled with more than 3.4 ounces (100 ml) of liquid through airport security. This is due to the Transportation Security Administration's (TSA) regulations on liquids, gels, and aerosols.
- Size Limitation: Any liquids in your carry-on must be in containers that are 3.4 ounces (100ml) or smaller.
- Sealed Baggie: All liquids must fit into a single, clear, quart-sized zip-top bag.
Empty Bottles are Allowed
According to the provided reference, you CAN bring an empty bottle through security. This allows you to:
- Reduce waste: By bringing your own reusable bottle.
- Save money: By avoiding buying bottled water at inflated airport prices.
- Stay hydrated: Fill your empty bottle at water fountains or refill stations within the airport after you pass through security.
Exceptions to the Liquid Rule
While the 3.4 oz (100ml) rule applies generally, there are some exceptions, though they don't typically apply to general water bottles:
- Medically Necessary Liquids: You may be allowed to bring more than 3.4 ounces of liquids for medical purposes, but these must be declared to TSA agents.
- Infant Formula/Milk: You can bring a reasonable amount of formula or breast milk, often with some testing by TSA.
Tips for Bringing Water on a Plane
- Pack an empty reusable bottle: This is your best bet to have water on the plane.
- Fill after security: Look for water fountains or refill stations in the airport terminal, after you have passed through security.
- Consider buying water after security: You can always purchase water at an airport shop if you forget your empty bottle, but it may be more expensive than if you brought your own and refilled.
