Yes, you can cancel your American Airlines flight without a fee if you do so within 24 hours of booking. This policy applies to all fare types and is especially helpful if your travel plans change suddenly. After 24 hours, the cancellation fees depend on the fare class you booked. Basic Economy tickets are typically non-refundable and do not allow changes or cancellations without a fee. However, Main Cabin and higher fare types may offer more flexible cancellation options, including refunds or travel credits.
