Do I get a refund if I missed my flight?

You generally can’t receive a refund on a missed flight. Depending on the circumstances of your situation and the terms of your fare, you may receive partial credit or free rebooking, but the only way you’re likely to get a full refund is if the airline cancels your flight.
