It took 2 hours to book a flight because the website kept kicking me off, requiring me to re-enter my information every time I looked away for a minute or so. I downloaded the app hoping it would be more stable and instead got kicked for "inactivity" when I was literally on the app filling out information. What actually happened was that someone else picked my seat out from under me and Spirit kicked me off. Genuinely the most frustrated I've ever been trying to buy something online.

Spirit no longer accepts Discover as forms of payment. After verifying this, when my card kept being denied and then setting up a new form of payment, I lost the price of the flight I was purchasing. Very annoying because it seems many times, just as I am ready to purchase a flight, the price suddenly changes. I feel like once it is your cache you should be able to purchase at the price you were quoted, especially if you have already placed your card information in it!!

"Please wait" is the only thing you'll see when trying to get your boarding pass. It's. Slow. As. F. It also gave a weird error when trying to check in with confusing verbiage, and the closest I can get to making sense of it was that I owed them money? I had to check in on the web site and then let it hit their servers for about 30 minutes for it to show my boarding passes on this app.
