Sorry, you are not the winner of the 3M 720kb Floppy disk! The mystery owner of Spirit Airlines is ...drum roll please.... Northwest Airlines!! NWA owns around 20% of Spirit Airlines! NWA also owns 20% of Champion Air (formerly MGM Grand). The only way I can see NWA selling them is to finance the purchase of new aircraft. As we in the business world know the trickle down effect will happen, the old NWA aircraft will be written off the books and sold at "scrap value", they will be then be "sold" to Spirit and Spirit will depreciate the aircraft again, Thus NWA gets to buy the planes once, sell them twice and decuct the cost of the aircraft twice! See what 4 years of business school will do to a person!! Any more questions please feel free to ask.
