When traveling with American Airlines, you are able to take advantage of their complimentary checked bag service. This means that each passenger is able to take one small bag, which must be no larger than 22 inches by 14 inches by 7 inches, onboard the aircraft. This bag must be packed in a container that is either checked or carry-on luggage. Unfortunately, American Airlines does not offer a free checked bag for infants or children.

In addition, American Airlines offers a complimentary carry-on bag for each passenger. This bag must be no larger than 22 inches by 14 inches by 7 inches and must be packed in a container that is either checked or carry-on luggage.
