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!

Allegiant is a fine discount travel company but don't ever expect to be able to contact customer service. The phone number is perpetually busy, their online chat does not work and email, well...you get it. They are great to veterans, no doubt. But their customer service is awful. Case in point, no where in the app is there listed or noted any way to contact them. Not one.

This app would not pull my boarding pass up when I got to the airport.. last flight of the night, ticket counter was closed down, no one could print me a boarding pass. They weren't gonna let me on the plane. It was 3 minutes before departure when they pulled a ticketing agent to go to the counter. If the flight hadn't been delayed I would have missed it. UNACCEPTABLE!!
