Just a point on comparing the QF split up to the VA split up:
VA split Int'l and Dom into two separate companys to allow a foreign carrier to buy into the DOMESTIC airline.
QF Int'l is the company that needs the investment from a foreign carrier, yet as I understand it, QF Int'l must still remain not more than 49% foreign owned. Domestic is already immensely profitable, so why would you need a foreign investor??? Unless you can transfer that foreign capitol from Domestic to International, I don't see how this would work as a strategy.
I wouldn't get too excited about pilot jobs changing too much... there's already separate contracts/EBAs and I doubt this will change anything... yet.
