Sun Country Airlines has a cancellation policy that outlines the rules and fees associated with cancelling a flight reservation. Here are some key things to know about Sun Country cancellation policy:

1. Sun Country allows customers to cancel their flights within 24 hours of booking without penalty, as long as the reservation was made at least 7 days before the departure date.
2. If you need to cancel your flight after the 24-hour grace period, you may be subject to cancellation fees, which vary depending on the fare type and the timing of the cancellation.
3. Sun Country offers three types of fares: Wanna Get Away, U Fly, and First Class. Each fare has its own cancellation rules and fees.
4. Generally, the Wanna Get Away fares are the most restrictive, with higher cancellation fees and fewer options for changing your flight. U Fly and First Class fares offer more flexibility and lower fees.
5. If you need to cancel your flight, you can do so online through the Sun Country website or by calling the airline's customer service line. Be prepared to provide your reservation number and other information to verify your identity.
6. If you have travel insurance or purchased a refundable ticket, you may be able to get a full refund for your cancelled flight. Check your policy or ticket terms for details.
7. Sun Country may also offer vouchers or credits for future travel instead of a refund, depending on the circumstances of your cancellation.
