Sun Country Airlines Ticket Cancellation Policy especially helpful for travelers whose plans may change. If you cancel your flight within 24 hours of booking and the departure is at least seven days away, you're eligible for a full refund with no cancellation fee. After the 24-hour window, most tickets are non-refundable, but you can still cancel and receive a credit for future travel, minus any applicable cancellation fees. These credits can be used for a future Sun Country flight within a specific time frame. Refundable fares allow cancellations at any time for a full refund. In cases where the airline cancels or significantly changes a flight, passengers are typically offered a full refund or alternative travel options. Sun Country recommends reviewing the fare rules at the time of booking to understand what applies to your ticket. Travel insurance is also encouraged for added protection.
