Won’t work

This app is a piece of junk. I downloaded several different times and it still won’t work. Do you think the airline would be able to build an app that could actually work for its passengers?

Glitchy

Won’t work on IPhone SE

I’ve had this problem for two years now - I’ve uninstalled and updated the app several times and when I check-in for my flight I can’t get past the hazardous materials screen, and can’t complete the checkin. There is no button to click that says I understand about the hazardous materials. It’s beyond frustrating. Please fix this!!!!

FAQ

What can I do with the Sun Country Airlines app?

The app allows you to check in for your flights between one and 24 hours before departure, download your mobile boarding pass, manage your existing trips by adding bags or changing seats, and book new flights. You can also check flight statuses and access your loyalty account.

How do I get my boarding pass?

Once you check in, you can download your boarding pass directly to your Apple Wallet. This allows you to skip lines and head straight to security if you are not checking any bags.

Can I manage my flight details in the app?

Yes, you can find all your trips in one place within the app. From there, you can add bags, select your preferred seat, or adjust your flight details if your travel plans change.

Is the app free to use?

The app itself is free to download and use. While the app facilitates booking flights and managing trips, the cost of flights and any associated services like baggage fees would be separate purchases.

What information is available about my flights?

The app provides real-time flight status updates, so you can stay informed about any changes to your itinerary. You can also check the status of any flight to track when family and friends are arriving.
