Can i bring my water bottle on the plane

The rules around bringing water bottles on planes can vary a bit by airline and airport, but here is a general overview:

  • You are typically allowed to bring an empty water bottle through airport security checkpoints. Once through security, you can then fill up the empty bottle at a water fountain or concession.
  • Bringing a full, sealed water bottle through security is also generally permitted, as long as the bottle is 3.4 ounces (100ml) or less in size. This falls within the TSA’s 3-1-1 liquid rules for carry-on bags.
  • Larger water bottles over 3.4 ounces are usually not allowed through security checkpoints, unless the water is needed for medical purposes. These larger bottles would need to be packed in your checked luggage.
  • Some airlines may have additional restrictions on the types or sizes of water bottles permitted onboard the aircraft itself. It’s a good idea to check the specific policies of your airline before your flight.
  • Reusable water bottles made of metal, glass, or certain plastics are generally allowed, as long as they are empty when going through security.

The key is to be mindful of liquid volume restrictions for carry-on items, and to pack any larger water bottles in your checked luggage if possible. Let me know if you have any other questions!
