I fly Spirit all the time. The only thing that stinks is their fare structure. They charge for everything. I’m surprised they didn’t charge an additional fee for flying to an alternative airport.
I fly Allegiant out of Lax frequently. They’re the only line that has a straight flight to Bentonville Arkansas or Springfield Missouri. Same thing. They charge for every little thing. A $200 ticket winds up over $300 by the time you’re done with all the taxes, fees, and their add ons.
