Liquid + Luggage: Get the Lowdown on Bringing Liquid On A Plane

What is the maximum amount of liquid I can take in my carry-on?

3.4 ounces is the most liquid you can have in a single container in your carry-on. It’s important to note that it must fit in a quart-sized bag and you should separate the bag from your carry-on luggage when it comes time to go through screening.

How many liquid containers can I bring in my carry-on?

You can bring as many containers as you can fit in your quart-sized bag.  The bag must be able to close.  Only one bag is allowed per passenger.

Are there any exceptions?

There are two exceptions. Medications and child nourishment such as formula are permitted in reasonable amounts.

Can I bring more liquid in my checked luggage?

Yes, you are allowed to pack larger containers with liquid in them in your checked luggage. The TSA does not restrict the size of containers in your checked luggage.

What if I have a container that is larger than 3.4 ounces but only contains a small amount of liquid?

You would still have to pack that container in your checked luggage. The size of the container determines whether or not it is allowed in carry-ons, not the amount of liquid.

Where can I find the official rules about liquids on planes?

The information above was current when this was written but the best place to find all the rules related to carry-on luggage is the TSA website.
