How to Cancel a Non Refundable Flight on Midwest Airlines
- 1). Cancel your non-refundable ticket either online or by calling Frontier Airlines' reservation department at 800-4321-FLY (800-432-1359). Note the cancellation confirmation number the reservation specialist provides, and retain the original ticket confirmation number. This cancellation must be completed before the original scheduled departure date.
- 2). Call Frontier Airlines' reservation department when you are ready to rebook a flight, within one year of the original cancellation. Make sure to have the original ticket confirmation number and cancellation number handy.
- 3). Rebook the flight for a date within one year of the original cancellation with the reservation specialist. You may be forced to pay a ticket change fee, but your ticket will be valid for the original destination and transit route, with its original value retained.
