There is a bleeding good reason why QANTAS major competitors now all have big fleets of twins.
With fuel representing 30% of operating costs it is bleedin' obvious, except to the smartest guys in the room..
Quite simply, if QANTAS had carried the same AKTM as in recent years, in B777/787 on long range operations, instead of B747/A380, it would not have made the big losses it did, and the current profits would be correspondingly even better.
Just maybe the tide is going out and we will see the little fella swimming naked...Sorry for the imagery
