Forgive me for saying this but the only venture so far in these troubled times that is reputably somewhat stable; is Jet*.
Any Blind (and deaf and dumb) Freddie will be able to come to a pretty quick conclusion that premium markets will suffer and low fares will prosper when there are times of economic stress. No one can dispute that.
The big worry is that when the economy finally picks up again, will Qantas ever grow the Mainline product to at least (and beyond) the level it is at now...I fear not. It's given Joyce a perfect excuse to consolidate the Jetstar LCC model during the downturn, and then ramp it up when times are good, all the time neglecting the high yield end of the business.
