I can't book a flight on the app. It gets to the packages options and says "Something went wrong" no matter what option I choose. This has happened the past couple time I've tried booking a flight and end up having to book through the website. I'm pretty sure I've lost out on points doing it this way. What is the point of advertising the app and getting points when booking on it when it doesn't even work? *Almost 2 years later and with all the technology in the world this app is still trash.

9 times out of 10 I can guarantee some kind of issue with this app. I fly FREQUENTLY with them so it would be nice to have reliability with this app. My current flight wasn't showing up in the app called the priority line and got absolutely nowhere. Absolutely ridiculous with the amount of money I spend with this airline . I have to use them cause they're the closest airport to my house.

Buttons on app to book flight and manage trip do not work. Disappointing that after 5 years & several updates, there is no improvement. This app is terrible. It will not allow me to check in on the app. I can do it online from my mobile, but not from the app. Since my mobile is not connected to a printer, I have to pay at the counter to get a boarding pass. worst app ever!
