Spirit is DEFINITELY the BUS of the airline industry. They have low prices because they charge for everything, seat, carry on bag, checked bag etc if you need it they charge for it. I was afraid to ask for water. What’s obvious is that in a further attempt to maximize profit they’ve have NO room between rows. I’m 6’2” and couldn’t sit down with my legs in front of me. There was a guy across from me who was about 6’6” who couldn’t sit down AT ALL. I WILL NEVER EVER EVER AD INFINITUM fly Spirit again. If I just have to be somewhere in a hurry I’ll drive first and risk a speeding ticket. RIDICULOUS!!!!
