Frontier Airlines’ refund policy varies based on the timing and reason for the flight cancellation. If you cancel within 24 hours of booking, you might be eligible for a full refund. If Frontier cancels the flight, a refund or rebooking is typically offered. For cancellations made after 24 hours, refunds are less common, though you may be eligible for a travel credit. To start the refund process, visit Frontier’s website and follow the steps under the cancellation section. Review your booking’s refund rules before canceling.
