If you have to change your flight for any reason - including my case where Spirit Airlines set the travel itinerary for the wrong date - you will not receive a refund. You will likely be issued travel credit - but that credit is designed to be unusable. I tried to book the flights I wanted but was told they were not available, and would not be available until sometime after the travel credit was set to expire. They refused to extend the travel credit to make it right - and this is after they promised me multiple times that I would be able to use this travel credit for the dates I wanted.
Spirit Airlines is a scam!
