Frontier Airlines

Just awful. There is NO WAY to avoid using this terrible app, and at times it forces you to add upgrades/apply for their stupid credit card in order to proceed through the booking steps. I am signed up to earn miles for trips, but for some insane reason, my mileage number never seems to attach to the flights I pay for. This seems like something that you'd be able to fix in the app, but when I try to add the details manually, I get an error message. This has happened despite multiple attempts.

I had to remind myself why I fly Delta. The app won't allow me to check in because of server problems (it's been 5 hours). The help chat crashes or just doesn't work at all. So I called the customer service line and basically was told, oh well, figure it out. keep in mind the app is the only way to check in. Save yourself the trouble and fly something else. This company does not value your money.

I recently tried to change a return flight date and it was just impossible. I followed the apps' prompts and when I checked the "direct flights" box, all the flights shown were from my initial departure airport instead of the return flight airport. When I finally got that figured out and selected the correct flight from the correct airport and hit "continue" I got a blank white page with a loading wheel and then nothing. After several minutes, the app redirected me back to my itinerary page.

tried several times on both the app and the website to book over the course of 20mins. It kept failing with errors. log me out several times. each time I started booking, I made no changes at all, kept selecting the same flights (premium) started at $550, then I went up to $590, Then finally the last time I tried to book a flight it let me through to the booking page and ended up at $700. total scam.

the only thing worse than this app is the terrible airline it's associated with. the app is buggy, won't let me add my own trip (cuz it says I'm not a passenger despite totally being a passenger). So good luck boarding the plane without a "CURRENT" boarding pass. Spoiler: a screenshot one won't work because Frontier and their App team want to make the experience as unpleasant as possible. I'm switching back to Southwest. This airline and their app are total trash. Can't wait to get rid of both.
