Sounds like what the business is going to turn into is airline "churning." Do a start up, pay ultra low wages to desperate workers, ride the tiger for a while, then shut it down and start all over again. Corporate officers walk away with zillions and everybody else gets a pink-slip and a new job at constantly lowering entry compensation.
Predict we'll have the same thing here. JB is riding the tiger now. In a few years, after Virgin USA and some others . . . . then JB is bust. You can then fly for JetPink, JetYellow, etc.
In the meantime, air service to marginal cities that the cherry pickers like SW and JB, and soon to be Virgin USA don't want will cease.
