How American’s policy compares with Delta, United and Southwest
American Airlines has narrowed its 24-hour cancellation policy, ending a more generous refund option for passengers who book flights close to departure. Previously, tickets purchased at least 2 days before departure could generally be cancelled within 24 hours for a full refund, regardless of fare type. American’s customer service information now says tickets must be purchased at least 7 days before departure to qualify for the 24-hour refund option. That means passengers booking a flight less than a week before departure can no longer rely on the same automatic 24-hour cash-refund window if they change their plans shortly after purchasing. Department of Transportation, which applies its 24-hour refund-or-hold rule only to tickets purchased at least 7 days before departure. Department of Transportation, airlines must provide passengers who purchase a ticket at least 7 days before scheduled departure with either a full refund when they cancel within 24 hours of purchase or the option to hold the reservation at the quoted price for 24 hours without payment. American’s previous policy extended the 24-hour refund option to some tickets purchased only 2 days before departure. Under the revised terms, that additional flexibility is no longer available for bookings made less than 7 days before a flight. American’s revised policy puts it closer to the standard 7-day requirement already used by several major U.S. airlines. United Airlines, JetBlue and Southwest also apply the federal 7-day advance-purchase requirement to their 24-hour cancellation policies, according to Afar. Delta Air Lines remains more flexible, with its 24-hour risk-free cancellation policy applying regardless of how far in advance the ticket was purchased, provided the cancellation is made within the airline’s specified 24-hour window. View From The Wing reported that American’s Conditions of Carriage had been updated to reflect the 7-day requirement while another section still contained language referring to refunds for tickets purchased at least 2 days before departure.
Because different versions of American’s published terms have not always appeared to reflect the same policy simultaneously, the transition has also created uncertainty. For travellers caught during the changeover, the terms displayed when the ticket was purchased could therefore become important.
According to the U.S. The change brings American’s policy in line with the minimum requirement set by the U.S. Airlines can choose to offer more generous cancellation policies, but the federal rule establishes the minimum protection that applies across the industry. The difference matters most for travellers booking close to departure. Under American’s previous policy, someone buying a flight several days before departure could book immediately and still have a full day to reconsider. Under the new terms, that same traveller may have to rely on the fare’s ordinary cancellation or credit rules instead. Passengers who believe they were promised a refund should keep copies or screenshots of the fare conditions and refund terms shown during booking.
The airline had previously offered a more generous window for some last-minute bookings.
