Agreed. I make decent money as a software engineer but I've probably flow 50+ times with Spirit. Like you said, they are predictable and reliable. What I appreciated about their staff is that they were extremely friendly but also capable of putting entitled people in their place. Oftentimes on AA and United, assholes got their way but on Spirit, they squashed it fast.

The only people surprised by Spirit were people who don't read warning labels and then you should only be surprised once. Heck, I paid 3$ for coffee on spirit but they would gladly bring refills and were proactive about almost like a restaurant. On AA and United, you usually had to go up and ask.

On top of that, you could get the big front seat (tm) which wasn't first class but pretty good about 150$ if you waited until your flight to bid. I got it a bunch and it came with free snacks and drinks and it was much cheaper than buying business

I'm gonna miss it.
