Booking a flight on the website and then being told I need the app just to see my boarding pass drives me nuts.

If it's frontier, as much as they want to make you think you need the app, if you lookup the trip manually on the site (using your confirmation code), you can download it from the web

I can sort of understand that - device attestation and all. And it's still a choice since you can go to the airline's counter at the airport to get a boarding pass.
