If you wish to cancel your Spirit reservation first go through Spirit Airlines Cancellation Policy, you must do so 24 hours prior to the actual boarding time of your flight. You will receive a full refund without incurring additional charges for cancellation fees.
You can also get a refund for the ticket price by simply requesting the reservation fee provided at the time of booking.
Before applying for a refund for an Spirit cancellation, check whether the ticket is refundable. This is because flights have specific policies for specific tickets and not all tickets have a refund policy.
Tickets marked 'Non-Refundable' or 'Non-Refundable' clearly imply that no refund will be provided for the reservation for ticket cancellation.
In general, no refunds of any kind will be issued for cancellations made on Spirit airlines promotional or marketed tickets.
