Frontier Airlines provides refunds for cancelled flights, but the policy varies based on the ticket type. If you purchased a refundable ticket, you are eligible for a full refund upon cancellation. For non-refundable tickets, however, Frontier generally does not issue cash refunds, but you will likely receive a travel credit or voucher that can be used toward future flights. One important rule to keep in mind is the 24-hour risk-free cancellation period. If you cancel within 24 hours of booking, you are entitled to a full refund regardless of the ticket type, provided your flight is scheduled at least seven days out.
