I wouldnt be so sure that the 744 flying will be available to QF LWOP crew.....
The guys at EFA will get first option, as they should. While it makes more sense (from one perspective) to let the QF 744 guys swap over, it is a separate operation. If QF had new 737's, and EFA had a surplus, would we allow EFA crew to just come across? I bloody hope not. QF SO's etc should get first options.
As has been said, at least the option for LWOP is there (whether it be 737/767 or 744). Much better than being given a blanket 'NO', as per Jetstar 2004......
