QF is behind the 8 ball competively for one other reason...Australia's geographic location and distance from everywhere...Oz is the end of the line...compared to Dubai which is currently and for a fair while yet a hub.
It is entirely likely that QF is incapable of the type of effeciencies that EK get from their crews...no fault of anyone at QF least of all the crews...not only are QF battling those sorts of issues but also competing with companies that would not be allowed their 'work practices' in a first world country...but that is an issue for CASA and their track record in this area is abismal.
None of this is a justification for the sort of behaviour we have come to expect from GOD.
