if the 767 is retired earlier, would it be possible for QF to convert 787 orders to 737's to pick up the slack? I know the current 737's are not being utilised anywhere near their optimum amount but to keep the flexibility, maybe more planes required..
From the rumour I heard, the 717's are going to operate on some of the routes the 737 used to fly on (Canberra and hobart routes) which will free up some 737's to fill in for the capacity lost by retiring the 767's.
