Never fly Spirit or any other discount airline. For land travel, the bigger the vehicle the better. No sleeping on the ground, in a tent, or in a car. It's got to be comfortable.
From what I've seen happening at the Spirit terminal at one of Houston's airports, it's not about the cost - it's about the overbooking, the chaos at boarding, and the lack of organization in just about every other aspect at the airport.In defense of Spirit in particular, you just have to book with the expectation that you're going to pay a lot more than advertised. If you do then you can actually have a much better experience than the same amount of money at a lot of competitors. IOW if you can only afford $400 per ticket, booking Spirit can get you a lot further, with a lot more comfort and perks, than spending the same amount on United, American, and a lot of other airlines.
From personal experience, the travel itself wasn't bad. But my internal clock was messed up for a week. Flew HKG-NRT-LAX-YYZ. Was definitely drinking beer at 10am in LAX.For example never going on a 24 hour plane trip
My rule is, never pay to stay anywhere that is "worse' than what I have at home lol. So, no camping, no crappy hotels.
