Generally, Frontier Airlines tickets are non-refundable. However, there are exceptions. ✅ You can get a full refund to your original form of payment if you cancel within 24 hours of booking, and the flight is scheduled to depart 7 or more days from the booking date. For cancellations outside of this 24-hour window or for flights within 7 days of booking, you will typically receive a travel credit for the value of the ticket (minus any applicable fees), according to Frontier Airlines.
