You can cancel most flight bookings online. For some airfares, if you cancel within 24 hours, no penalty fees apply.
If you cancel a non-refundable flight reservation, the airline may issue you a flight credit for a future booking instead of a refund. For more information, please read Use your flight credit. Some flight reservations are not eligible for a flight credit after cancellation. If you cancel one of these reservations, you will lose the value of your ticket.
Before you cancel your flight, review the Airline Rules & Regulations portion of your itinerary for any airline cancellation fees. Any applicable fees are always charged by the airline, not Orbitz.
