Spirit Airlines, like all airlines, has a cancellation policy in place for its customers. Spirit airline cancellation policy outlines the rules and fees associated with cancelling or changing a flight reservation. Generally, Spirit Airlines allows passengers to cancel their flight within 24 hours of booking without penalty. Beyond that time frame, fees may vary depending on the fare type and destination, but generally can range from $90-$200 per person.
