If you travel lite with clothes in a book bag(wash clothes if extended stay)… I don't see why anyone would fly United, Southwest, American Airlines, etc VS.the budget Airlines like Spirit. Maybe if you have points with those airlines… Otherwise, save hundreds of dollars using budget airlines which the planes are newer in my experience, and never had a bad experience versus my recent bad experiences with Delta and the…
You must have buns of steel. I flew Spirit exactly once (well, twice, it was round-trip), and it was such a miserable experience I swore to never do it again. Their seats are made of concrete as far as I can tell. For domestic flights I pretty much always sit in the window and never get up during the flight. On spirit I had to get up and walk around after about 3 hours 'cause my ass was sore. Never again.
