They canceled my flight and never told me. There was no follow up email. I had to buy another ticket the day of.

It was a full Spirit experience. Got to witness police officers having to deboard a passenger and cost us about an hour of delay. Front seat was spacious and better than expected.

Bad airline to travel with my flight was delayed for more than 3 hours they act like it’s normal

flight delayed because of poor staffing and organization - confusion from gate agents and flight attendant supervisors scheduling a missing flight attendant. flight delay 1 hr 30 min

Overall, it was nice. My only complaint was that I purchased WiFi, and it only worked for a fraction of the flight. Everything else was great

My flight was delayed by over an hour and the turbulance was horrible.

This flight cancelled. I am in the airport right now and my kids sleep on the floor. We are waiting for information in the line 4 hours and rude woman from spirit airline offers us flight to Austin on 23 February. No water no food offer. The offer to book hotel and they will refund 150$. The nearest hotel 450$ per night. So I got flight to San Antonio 02/22 at 7am. I hate this company, they are rude and no empathy. So many people with kids were there. And I don’t sleep and it is cold here. I don’t have warm clothes for me and my kids. And I don’t have money for transport from San Antonio to my Austin.

The flight was delayed over an hour which got us into DFW at approximately 2:20 am

Terrible. Spirit cancelled the flight with 3 hours notice and were absolutely no help getting another flight. Had to make my own reservation on another airline and arrived in Dallas 12 hours later.

They cancelled the flight due to crew unavailability. The next day they cancelled the flight again.
