If your duty-free purchase of liquor, perfume, cosmetics, or any other item contains liquids, gels, or aerosols; and the container is larger than 100 ml (3.4 fluid ounces), you have to follow specific procedures to ensure that your items will not be confiscated.
Rules vary by country, but in general, one of the following will apply to you:
- If you can put it in a checked bag before passing through airport security, you don't have to take any precautions.
- If you purchased the item after passing through security, and you are on the last leg of your trip, you can put the item in your carry-on bag.
- If you purchased the item after passing through security, you are not on the last leg of your trip, and you have to pass through airport security before getting on your next flight (standard procedure if you are entering the US), you may have to place it into a checked bag prior to your next flight.
For additional details on dealing with the last situation, visit the duty free shopping advice page for details on how to fly with duty free liquids, aerosols, and gels.
In addition to the restrictions of the TSA, your airline may also have restrictions on what is allowed on the airplane. If you are carrying an unusual item, or if you thing that an airline may have a restriction, be sure to contact your airline ahead of time, or to contact a representative in the airport. Also, in the event that an airline loses your bags and finds them later, they may have limited luggage shipping options for getting your bags back to you, especially if you are traveling overseas.
In this video from the Conversation at AirSafe.com, you will get an overview of what is allowed and not allowed either in carry on or checked baggage. You'll also get advice on how to avoid the most common airport security hassles.
