Horrible! Flight was canceled 15 mins before take off due to mechanical issues. I  had a feeling that was going to happen since the plane never showed up. In addition, I had to stand in line for an hour just to get a refund. Some people had to take flights the next day since they were fully book the rest of the day, but I wasn't about to ride on a potentially dangerous plane. Good thing i booked a flight with southwest while waiting in line, which was an hour later than what would've been my departure time with spirit. \n\nSpirit did offer a $50 voucher for my next flight, but required me purchase a round trip ticket, which I wouldn't risk having another incident like this happen to me again...no thanks!
