Last thing I want to do is pay for a cramped seat that does not recline, no entertainment, stuff any small item underseat in front, (ALL baggage is fee-assessed). I won't pay $3 for mini water or a snack for 3 hr flt. Possibility of no back-up aircraft/crew and no interline options--then, poof, ticket is useless. Nor do I wish to be herded like cattle by surly cabin cowboys. The horror stories of Spirit service and comfort/cleanliness are infamous! Check tripadvisor air travel forums.
