A few important points are included in the Sun country ticket change policy. Let's take a look: you will not be allowed to change the flight ticket date if you have not made the bookings via the official website. If you have missed the flight and want to change the date for the same, you will not be allowed to get the same done. Also, if you have made the bookings via any travel agency, then you will have to contact the travel agent for the same. The official website of the customer service team of Sun country will not be able to help. These are some of the rules that are included in the Sun country ticket change policy.
