Frontier Airlines cancellation policy allows passengers to cancel flights, but fees may apply depending on the type of ticket purchased. For standard tickets, cancellations made within 24 hours of booking are eligible for a full refund, provided the flight is at least 7 days away. After 24 hours, cancellation fees range from $39 to $79 depending on the fare. The airline also offers a "Cancellation Protection" option at the time of booking, which allows passengers to cancel for a full refund for any reason. Non-refundable tickets generally don’t allow for refunds, but credit for future travel may be issued.
