I just flew from New Orleans to Vegas on Spirit in March.
It was just me and my 7 year old who had never flown before.
It was fine. No issues at all.
Definitely no frills, so if the drinks and snacks are important to you, you won't like it.
It's slightly cramped, but definitely no worse than flying on one of those Canadair jets out of Jackson.
I would still recommend paying a couple bucks extra and getting the larger seats up front if they're available.
The only problem I have Spirit is that they are a "budget" airline, but they will nickel and dime you to death.
Carry-on (other than personal item like backpack,laptop, purse, etc.), checked bags, seat selection - all cost extra.
But if you're going on a short trip and don't need to check bags I think it's just fine.
Anyone flown Spirit? I can't tell if the reviews are from spoiled *****, or if it really is that bad. I'm flying from New Orleans to Miami, so it's not a long flight and it's the upgraded seating. Everyone is bitching about not getting free water and snacks, but it seems like the best way to solve that is to bring a water and snack with you. Delta flights would be close to $500 more for two tickets and there would be a layover. Is the money saved worth it?
