• Tickets in the basic economy are subject to this policy. The refund money normally starts to be processed and is credited to your account within seven to ten business days.

• You will be responsible for the cancellation cost after this 24-hour risk-free period. This would depend on the ticket's class and price.
• According to American Airlines cancellation policy, you won't be charged a cancellation fee if you cancel your flight within the next 24 hours after booking your reservation. This rule applies to all sorts of tickets, regardless of price.
