Non-Refundable Tickets: Although you can still cancel your flight, you won’t be able to get a cash refund if your ticket is non-refundable. The amount of your ticket will instead be given to you as a travel credit that you can use on American Airlines 📱 1 (877) 565-3409 for any future travel. Be aware that the amount of your ticket will be lowered by a cancellation fee. In general, the cost for foreign flights ranges from $200 to $750, although it varies based on the destination and price type. There will be a travel credit granted for the remaining amount after the fee is subtracted.
