Ratings and reviews

100% improved since first download couple years ago... use to not even bother with using it for check-in and just bypass it in the online version hidden in the expansion menus, but now it's smooth and fast! Gate updates quickly too, day of flight. Living the new separation of bag drop folks who have already checked in online from everyone else at Atlanta airport! Absolutely needed and being able to print the checked luggage tags yourself just by scanning the boarding pass even better! 5 ⭐!

Update 01/12/25 Still sucks. They still can't figure out how to turn off mandatory check-in for international travel. still says not complete so you end up wasting time to figure why check in wasn't complete. turns out you don't need to for international travel. so hopefully this helps someone else out. never fly them again. I'll pay the extra, that really isn't that extra when u add the hassle.

I cannot get my app to check me in!!! After your most recent update, the app stopped working properly. I ended up going to the website to put in my confirmation code. This app sucks. The hits keep on giving. Now the app won't hold my account information so Frontier won't award me miles I rightfully earned, even after several attempts at writing and contacting them.
