Hasn't this been the master plan from as far back as just after QF management were shown it could be done in 1989?
1. shrink the (expensive in staff terms) 'legacy' Qantas to a small as possible rump
2. any expansion goes to LCCs like Jetstar
3. once the QF rump is so small that it can be closed down without too much pain* if the remaining (expensive) legacy staff won't accept the (inevitable) "offer they can't refuse" to work to Jetstar T&Cs, make that offer, shut down the 'rump' (whatever that costs) and..
4. re-brand Jetstar as Qantas (or maybe not, as by then, the brand will be so thrashed it might not be worth the new paint jobs) and Bob (or should that be Alan)'s your uncle!
* remember, in defining 'pain', you're dealing with a man who blithely shut down the whole operation without warning in what could only be classified as questionable circumstances.
I've seen the burn/payload comparisons between the A380 and B777. How any management without a hidden agenda could go the A380 route when most of their competitors are operating the 777 is totally beyond me.
