What Size Empty Water Bottle Can I Bring on a Plane?

Whether you’re flying for business or pleasure, staying hydrated is essential. But what happens when you’re stuck on a long flight without access to water? Can you bring your own empty water bottle on board?

The answer is yes, but there are some restrictions. In this article, we’ll explain the rules for bringing empty water bottles on a plane, as well as some tips for staying hydrated while you’re flying.

What are the rules for bringing empty water bottles on a plane?

The Transportation Security Administration (TSA) allows passengers to bring empty, unsealed water bottles on board a plane. However, there are some restrictions on the size of the bottle.

Bottles must be 3.4 ounces or less

This is the same size restriction that applies to liquids in carry-on bags. If your water bottle is larger than 3.4 ounces, you’ll need to pack it in your checked luggage.

Bottles must be clear

The TSA also requires that empty water bottles be clear so that they can be easily inspected. This means that opaque bottles, such as colored plastic or glass bottles, are not allowed.

Bottles must be empty

Finally, your water bottle must be empty when you pass through security. You can fill it up once you’re past security, but you cannot bring a full water bottle through the checkpoint.

Tips for staying hydrated while you’re flying

Even if you’re allowed to bring an empty water bottle on board, it’s a good idea to have a backup plan in case your bottle leaks or gets lost. Here are a few tips for staying hydrated while you’re flying:

  • Drink plenty of water before and after your flight. This will help to prevent dehydration.
  • Bring a reusable water bottle that you can fill up at the airport or on the plane. This will help you to reduce your environmental impact and save money.
  • Ask for a cup of water from the flight attendant. Most airlines will provide water to passengers upon request.
  • Buy a bottle of water from the airport or on the plane. If you don’t have a reusable water bottle, you can always buy one at the airport or on the plane. Just be sure to check the size restrictions before you buy.

By following these tips, you can stay hydrated and comfortable during your next flight.

Liquids include water, drinks, lotions, sunscreen, makeup, and other personal care products. Gels, aerosols, and pastes are also considered liquids.

There are a few exceptions to the TSA liquids rule. You can bring larger containers of liquids if they are:

  • In your checked luggage
  • For medical purposes
  • For baby care

If you have a liquid that is larger than 3.4 ounces, you will need to pack it in your checked luggage. You can also pack liquids in your checked luggage if you have a doctor’s note or a baby formula package.

What Other Liquids Are Allowed in Carry-On Bags?
