This has been next to the worst app flight experience. Spirit holds the title for having a useless app and nickel & diming a customer to death, expecting you to pay for everything including selecting a seat. Apparently, Southeast doesn't believe in picking a seat. It's all about the luck of the draw and their open seat policy. You can't even just simply view your boarding pass. Every time you open the app, you have to check in again just to see your boarding pass. App is pathetic in today's age.
