> I liked Spirit because it was more akin to riding the bus
This is exactly why I would never be caught dead on Spirit. Sartre got it right, "Hell is other people." My issue with Spirit and other budget airlines as a frequent traveler was never about the planes, the staff, or the operations, it was always the other passengers. It's bad enough dealing with people in general in the circumstances we all find ourselves in stuffed into an airplane, but budget airline travelers are generally exactly the sort of folks who ride the bus, which is why nobody wants to ride the bus in the US.
I say all this as someone who enjoys public transport when I'm in Europe and has no problem flying budget airlines in Europe like KLM Cityhopper or EuroWings, because everyone across society uses public transport and budget point airlines in Europe. In the US though, public transport and budget airlines are nearly only used by people who you'd rather not be stuck near for hours at a time for fear of being attacked, coughed on, or otherwise somehow harmed even if minimally which is entirely avoidable by just not.
I'm not paying hundreds of dollars for a glorified bus ride. I've had issues with passengers on other airlines too. There is no expectation of me as a passenger behaving a certain way, and therefore the likelihood of being mistreated by passengers or staff a like is low. As you noted, other people pay more thinking "higher class" people fly delta or whatever, and to protect that image and experience I expect mistreatment from staff and other passengers alike on those flights.
I would rather deal with someone putting up their nasty leg on the chair next to me, or listen to a movie with speaker on for the whole flight, than deal with rude flight attendants that won't respond to my needs, or dirty looks from other passengers because I'm wearing something comfortable.
Aside from what I see on social media posts though, I've never seen anything extreme like that flying on spirit in all the years.
