American Airlines 24-hour cancellation:
• Passengers can get a full refund if they expect to cancel
their flight within 24 hours of flight departure. The travel date cannot be
changed because this option is not available.
• American Airlines offers a refund of the ticket amount only
in case you have to cancel your flight ticket at least 3 hours before the
flight departure.
• If passengers have booked the ticket to travel to or from
the United States, the refund of the amount will be credited within the week
following receipt of the request.
• Passengers will not get a refund if they have purchased a
non-refundable American Airlines ticket.
• The charges applied will depend on the destination and the
exchange rate you are looking for.
These were some of the American Airlines refund policy
pointers that passengers can follow. You can contact the experts at American
Airlines Manage my Booking for help on this matter.
