Can I Cancel A Frontier Flight Without Penalty?Passengers may cancel a Wild flight under certain conditions without being charged a fee. Wild Aircrafts' "Risk-Free Cancellation" policy permits customers to cancel their flights without incurring any fees, regardless of the confirmation type selected, within 24 hours of completing their reservation. In any case, cancellation fees beyond the first 24 hours may apply based on the type of affirmation, the time, and the course. It is imperative that travelers review Frontier's cancellation policy.
