They charged late fees for selecting seats (no $0 options). They also changed my gate within the last half hour and are refusing to reimburse my costs to drive across the country with two small children in a rental car.

I was waiting in line for the restroom onboard, the flight attendant told me to step back two rows and stay on the carpet. She was rude and I expected a tik tok experience with me getting thrown off the plane. She was rude and frankly there was no where else to stand.

I needed a cheaper option than Southwest who are almost as bad as Spirit...did the check in the morning of the flight and assigned the last row, middle seat. Paid 20.00 at the airport for an exit row window in 19 and all 8 rows behind me which sold occupied on their seat map were empty....so they force to you to pay for a better seat....I was alone in row 19 and shortly after take off two huge fat people came and grabbed the other seats, I rang the call button for the attendant and said I paid 20.00 for this seat and they just moved in here...I either want to be reseated, or have them take their original seats or a refund of what I paid, the attendant made them move back to their original seats. Worst, worst worst airline in the air....never again, never again, never again.

gate agents with the different rules at the different airports. made me pay for my bag as a carry on instead of a personal item, yet it fit under the seat on the way from Indy to Ft Laud

We flew Spirit because it was cheaper but the seats were so uncomfortable. I don;t need to be fed snacks on a plane but when it's a 3-4 hour trip then at least a drink is nice. The flight attendants had nothing to do the whole flight except for gossip loudly to each other right behind our seats, and they talked so much my husband couldn't even rest! I was fine with no tv or entertainment but the seats were so uncomfortable with no recline, no padding, and I am short but even for me to leg room was tough for a 3-4 hour trip. We probably would fly spirit again if we had to, but it's definitely not our favorite!
