Spirit Airlines Cancellation Policy <a href="https://airlinesupdates.com/blog/spirit-airlines-cancellation-policy/">Spirit Airlines Cancellation Policy </a> guarantees a full refund if you cancel your flight within 24 hours of placing your first reservation and at least 7 days before the scheduled departure date. When the 24-hour cancellation window has gone and you still want to change your Spirit Airlines flight reservation, there can be a fee and no refund will be granted (depending on how soon you cancel your booking). You can cancel your Spirit Airlines reservation made through Alternative Airlines and still get a full refund if you get in touch with us during regular business hours and within the allowed 24-hour cancellation window.
