Such a frustrating app. On every click you have to wait atleast 10 to 30 seconds. And they push us to app while checking in from the browser. If they have so much slow app why are they pushing us to check In flight on to app. Give both the options. Such a waste of time with this app. Update : it became more worse app not even loading anything, installed, uninstalled cache cleared. Nothing working.

Frontier requires the app and there is no ticket agent at this specific airport. Frontier changes and delays cause a lot of confusion and trouble. The gate agents are not helpful. Why does it seem like they hate their job? Forced to download the app and use it. The app did not clearly show that the second leg of the flight was 24 hours later. Was not able to get a credit, had to buy another ticket to get to destination.

When adding checked baggage to my departure flight, the app asked if I wanted to add the same to my return flight. I said yes, and it reflected on my booking details. I confirmed this several times because I didn't want to be charged a higher fee at the airport. I got to the airport and suddenly it's not in my booking and the desk agent didn't see it either. And I had to go online, not the app, to re-add the bag. Useless and frustrating, just like Customer Service.
