I dabbled in a few business classes at the community college But I do know that a new fleet type (mx parts, cross-training mx, training pilots, lost utilization from plane swaps and crew swaps, etc) is a whole new cost structure that Spirit isn't ready for, nor competent enough to take on. There's a reason why SWA was very successful for so long (and still mostly is), and it wasn't just fuel hedging, 1 fleet type is probably the most cost-advantage way to operate, and Spirit screwed the pooch on that one. (unless they have something in the works to obtain more Airbus)
