Sun Country Airlines offers a flexible cancellation policy, allowing passengers to cancel their flights within 24 hours of booking for a full refund, as long as the flight is at least 7 days away. After the 24-hour window, cancellation fees apply, ranging from $39 per flight segment if canceled 14 to 59 days before departure, to $70 per segment if canceled within 13 days of the flight. Refundable tickets are eligible for a full refund, while non-refundable tickets may receive future travel credit instead of a cash refund. Passengers can also purchase a Change Fee Waiver, which allows one free change to their flight up to an hour before departure. Cancellations can be processed easily online or by contacting Sun Country Airlines Cancellation Policy customer service.
