Spirit Airlines typically imposes a fee for flight cancellations unless the cancellation is made within 24 hours of booking and the flight is scheduled to depart at least 7 days later. Fees vary depending on how close the cancellation is to the departure date, ranging from $49 to $99. To avoid these charges, passengers can purchase the “Flight Flex” add-on, which allows for a one-time modification without a fee. For specific information on your booking, visit Spirit’s website or reach out to their customer support.
