So far no airline in the history of aviation has cut its way to long term profitabilty. It is easy to cut wages, the hard work is managing the in a system wide and systematic consistant way, the tension between efficency and operational effectiveness and having the vision and intestinal fortitude to spend 1 dollar now to save 10 dollars down the road. Spirit unfortunately IMO is probably a flash in the pan that will eventually sucumb to the failings of its misguided fetish on cost savings at any cost......
The good news is at least in the mean time the pilots will at least have decent terms and conditions.
