Understanding the cancellation policy for American Airlines is crucial for travelers. The airline provides a 24-hour risk-free cancellation period, allowing you to cancel flights booked at least two days in advance without penalty. After this grace period, cancellation fees may apply based on your ticket type. If your flight is canceled by the airline, you can opt for a full refund or rebook to another flight. To clarify your options, visit the American Airlines website or reach out to customer support for further guidance.
