and the stock is up about 500% in one day, could there be some insider trading?

I’ve known Spirit since they were one DC-9 in Detroit.
Their business model depends on undercutting everyone else’s cost, and then trying to eke out a profit on the cheap cheap seats. They lose money because, well, they make bigger losses at volume.

They need to die a quiet death and let someone else try.

Which makes them look like the best deal going. But then when you go to actually use your seat, you discover the floating seat cushion and fold-out tray at your seat are an extra $10 each, the emergency oxygen mask service is $20, and if you want toilet stall privileges that's $10 upfront, or $25 if you pay at the time of use.

Okay, that's exaggeration for effect, but that is the idea. Also, the space on their flights is CRAZY small. Tiny seats, near-zero legroom. And most of the attendants have a bad attitude towards the customers, in my limited experience on their flights.

That's leaving aside that this is just ANOTHER instance of Trump's stupid actions directly costing taxpayers HUNDREDS OF MILLIONS (or BILLIONS). I got 100 internets to bet that the board at Spirit is full of MAGAts and campaign contributors as well. Because that's how the mob boss we current have as POTUS blatantly operates at all times. No way his admin gives them this bailout unless there's something in it for ME ME ME.

Fuck this, let them FAIL.

.... you were exaggerating. I was believing you for a while there!

They nickle and dime the shit out of you so they can publish really competitive prices. To be fair though if you are going on a short trip and can fit all you need into a small carry-on, and don't mind being cramped (or you are a small person), they can be a decent option. For me the one thing they have going for them is they fly out of an airport that's VERY close to where I live, and the parking at this airport is much cheaper (though it's uncovered, so not the best when it's summer in PHX). So I've used them a few times. But I much prefer Southwest. More so back before they changed so many policies that used to make them kinda special in the marketplace, but at least SW still gives you more room, and the service is consistently better, with nicer attendants.

with Elon's tax money?

Free market capitalism, always thus.
