According to Frontier cancellation policy, if you cancel your flight within 24 hours of the time you booked the booking and at least 7 days before the scheduled flight departure date, you will be eligible for a full refund. If you cancel your flight during this 24-hour window, there are no cancellation fees. If you cancel your Frontier Airlines flight within the allotted 24-hour period, you'll still get a full refund even if you made your reservation through Alternative Airlines. Simply get in touch with us during business hours to request a cancellation or refund.
