Frontier Airlines Cancellation Policy allows travellers to cancel their tickets within 24 hours after booking for a full refund, as long as the booking was made at least 7 days before departure. Cancellation penalties beyond this grace time vary depending on the fare type and timing. Standard rates may carry a cancellation cost if cancelled after 24 hours, however "The WORKS'' bundle provides additional flexibility with no modification or cancellation penalties. Passengers on Frontier Airlines cancelled flights are entitled to a refund or the chance to rebook on another trip.
