Spirit Airlines Missed Flight Policy follows a strict no-show rule: passengers who miss their flight without notifying the airline in advance forfeit the full ticket value, including any return or connecting segments. Unlike some carriers, Spirit does not automatically rebook no-shows for free. To avoid losing the entire fare, travelers should contact Spirit as soon as they realize they'll miss departure — this may allow rebooking on a later flight for a fee, plus any fare difference. Acting quickly and always going through official Spirit channels (website or airport counter) is the safest way to minimize losses after a missed flight.
