Spirit Cancellation policy allows passengers to cancel their flights in case of unforeseen circumstances or changes in travel plans. The airline offers different options for canceling a flight, including online, over the phone, or at the airport.

Passengers who cancel their flights within 24 hours of booking are eligible for a full refund, as long as the booking was made at least seven days before the flight's departure date. For cancellations made after 24 hours, the refund amount depends on the fare type and the time of cancellation. 

Spirit Airlines also offers the option to modify or change flights, subject to availability and fees. Passengers can make changes online or by contacting the airline directly.
