Sun Country Airlines Flight Cancellation Policy offers flexibility for travelers who need to make changes to their plans. If you cancel your Sun Country flight within 24 hours of booking and your flight is at least 7 days away, you’ll get a full refund with no cancellation fee. After that, cancellation fees apply based on how close to your flight date you are. There’s no fee if you cancel well in advance, but if you cancel closer to your departure, you’ll pay a fee of $39 or $79 per segment. Refundable tickets are fully refunded, while non-refundable tickets may only be eligible for travel credit minus any applicable fees. If Sun Country cancels your flight, you’ll receive a full refund, regardless of the ticket type. You can easily cancel your Sun Country flight online, through the mobile app, or by contacting customer service. Sun Country also offers a Change Fee Waiver at the time of booking, allowing one free change or cancellation. In special cases like illness, military duty, or a family emergency, they may waive cancellation fees with proper documentation. Always check your ticket’s terms and cancel early to avoid unnecessary fees.
