Infants under the age of 2 traveling without a seat within the U.S., Puerto Rico and U.S. Virgin Islands do not require a ticket. Infants traveling internationally (including to Canada, Guam and Mexico) without a seat are required to have a purchased ticket and are subject to infant fares and taxes. When making your reservation, you should indicate that you are traveling with an infant, regardless of your destination.

Once infants turn 2, they are required to have a purchased ticket and occupy a seat. Infants who reach their second birthday after their outbound flight must have a purchased ticket and occupy a seat for their return flight(s).
