When canceling a Spirit Airlines flight, getting a refund depends on the type of fare you purchased and the timing of the cancellation. Spirit Airlines operates under a strict refund policy, typically offering non-refundable fares. However, there are exceptions. If you cancel your flight within 24 hours of booking and the flight’s departure is at least seven days away, you are entitled to a full refund. This is in line with the U.S. Department of Transportation's 24-hour cancellation rule.
