I think they are saying "weather" because it STARTED with weather. From what I've read, the storms on Sunday caused multiple cancelleations- which was true of other carriers as well. Apparently, Spirit has only the staff they need and the planes they need for the scheduled flights.....so when the flights on Sunday were cancelled, the planes and the staff (pilots and attendants) were not able to get where they needed to be for the next flight they were scheduled to service. And as more cancellations continue this just gets worse and worse. I've been watching flightaware and there is a plane set to take off from MCO headed to Philly that is now reading as "delayed" in Philly (scheduled to take off at 10, but still on the tarmac at MCO) . . .. it has been "taxing/delayed" for 2 hours now, those poor people on that plane. I bit the bullet and bought a one way ticket for each of us that will get us to Orlando earlier than planned with another carrier. I am not happy to be out the $$ I just paid, especially if our Spirit flight ultimately ends up NOT being cancelled, but I felt like I had to do it because I am watching all the seats disappear and prices rise astronomically for every other carriers flight on my route and even though I CAN....I just don't want to drive from Philadelphia to Orlando.
