Ratings and reviews

Not able to book flights in the app. The page does not load once dates are selected. I have been having this problem for months, there is no tech support of any kind for this app. This problem started around Nov 2025 for me, really makes having the credit card and points not worth it when you can't book a flight, and there is no support!

On multiple phones, our future flights were all displaying with the dates/times of our most recent flight ( in the past) and with arrived status. We called Sun Country and they do not have any tech support, nor does it seem they have any way to let the developers know there is a problem with the application. After uninstalling and reinstalling, the dates/times appeared to be working correctly briefly, but shortly after, we noticed additional problems with them stll being incorrect.

I randomly get logged out in the app, which happened today while I was in the security line (when the app also claimed I was offline, which I wasn't). I had taken a screenshot of my boarding pass and for some reason I could still access my boarding pass while logged out, so not ultimately a problem, but added stress at the airport isn't appreciated.
