Sun Country Airlines generally does not offer refunds for missed flights, especially if you fail to notify the airline in advance. In such cases, your ticket is often considered forfeited, and you may lose the entire value of your reservation.

However, if you contact Sun Country Airlines promptly after missing your flight, they may offer rebooking options, often involving a change fee and any fare difference. The availability of rebooking depends on the circumstances and the type of ticket purchased.

For passengers with refundable or flexible fares, there may be more leniency in rebooking or receiving travel credit. It's important to review your specific fare rules and contact the airline directly to understand your options.

If you purchased travel insurance, check your policy, as some plans may cover missed flights due to emergencies or unforeseen events, potentially reimbursing rebooking costs.

To minimize the risk of missing future flights, it's advisable to arrive at the airport well in advance, monitor flight statuses, and stay in communication with the airline regarding any potential delays or issues.
