For American Airlines flights, cancellations made within 24 hours of booking are free, provided the ticket was purchased at least two days before departure. After this, fees may vary based on ticket type. Refundable tickets allow for full refunds, while non-refundable tickets often provide only credit for future flights. Check your fare rules for exact details. Want to explore more? Check the American Airlines website or reach out to their customer service for precise guidance on your cancellation.
