American Airlines is known for being one of the most reliable airlines, but that doesn’t mean that they always provide refunds for cancelled flights. In most cases, if a flight is cancelled within the first two hours of the scheduled departure time, the airline will provide a refund.
However, if a flight is cancelled after the two-hour window has passed, the airline typically won’t provide a refund. In some cases, American Airlines will provide a refund if the passenger is able to get a flight on a different airline within a certain window of time.
