According to the American Airlines Cancellation Policy, refundable tickets can be refunded fully if canceled before the flight's departure. There will be a cancellation fee for non-refundable tickets, but the residual is returned in the form of a travel credit toward further travel. There is a 24-hour risk-free cancellation on all tickets, with a full refund if the ticket is canceled within 24 hours of purchase. For an award ticket, miles are returned; possible redemption fees may apply. If any airline has cancelled a particular flight, the passengers can have a full refund of their money or book again. https://www.americanflyhigh.com/blog/american-airlines-cancellation-policy/
