Can You Bring a Water Bottle on a Plane? TSA Regulations
The Transportation Security Administration (TSA) has strict guidelines regarding how much liquid you can bring on a plane.
You can only bring water through security if it’s less than 100ml. This is almost 5 times smaller than the average water bottle! Also, it’s worth noting that even if you only have 100ml in a larger bottle, it’s the size of the container that counts, and it still won’t be allowed through.
Yes, as long as it is contained within the quart-sized bag, it’s also important to note that these bags will be screened separately from your other items when going past security.
If containers are larger than 3.4 ounces (100 ml), they won’t be allowed through security, and the security officer will discard them.
However, you can bring an empty reusable water bottle of any size through security and fill it up after you’ve gone through the checkpoint. Of course, you’ll still need to ensure your empty bottle of water passing it through the x-ray machine.
It’s better to drink all liquids before you go through security and buy water inside the terminal or on the plane – or, of course, you could bring an empty water bottle and fill it up at the airport water fountains.
TSA Guidelines – Exceptions for Babies
The TSA also allows breast milk, baby formula, and juice for infants in reasonable quantities. To ensure your liquids can be taken on the plane, you must declare them for inspection. Once declared, the TSA will screen your items and allow them through if there are no security concerns.
TSA Exceptions for Live Fish
The TSA allows fish containers of liquid up to 48 ounces (1.4 L), with exceptions for larger amounts in some cases. The TSA also allows live fish on flights.
If you’re carrying a live fish, you’ll need to inform the airline about it in advance and make sure that your fish container is allowed on the airline you’re flying with. You will probably have to pay extra for this too.
Why Can’t You Bring Water Through Security?
The TSA’s restrictions on bringing liquids through security are in place for your safety. The restrictions limit the amount of liquid used as a weapon or to disrupt a plane. Limiting passengers from bringing large containers of liquid onto the plane reduces the risk of a security breach.
Can You Bring a Water Bottle on a Plane: Final Words
Being able to bring water on a plane can help make long flights more comfortable and enjoyable—but you must know the rules first!
Generally speaking, most airports allow passengers to bring one clear plastic bag of liquids carry-on luggage provided that each container is no more than 3.4 ounces (100 ml) and all containers fit inside the one quart-sized plastic bag.
The best option is to bring an empty water bottle and fill it up at the airport water fountains, buy water once through security, or even purchase water on a plane.
However, you may want to avoid airport prices. In that case, I recommend bringing an empty reusable water bottle to limit single-use plastic and save money simultaneously.
