Sun Country Airlines Ticket Cancellation Policy offers flexibility while keeping travel costs low. If you cancel your flight within 24 hours of booking and your departure is more than 7 days away, you are eligible for a full refund, regardless of the fare type. After the 24-hour window, cancellation fees apply depending on when you cancel, with fees ranging from $39 to $79 per segment, depending on how close to the departure date the cancellation occurs. Refundable tickets are eligible for a full refund if canceled before departure, while non-refundable tickets may result in a travel credit if canceled after the 24-hour period. Passengers can also purchase a change fee waiver to allow penalty-free changes or cancellations. Cancellations can be made through the Sun Country website, mobile app, or customer service, and it’s always recommended to review the specific fare rules at the time of booking to fully understand the cancellation fees and refund options.
