Rumour is that AA have cancelled about ten 777-300 slots and QF and BA are in contention for some of them (787 compensation - seen that type of thing before). QF on a one year ramp up to get some (or all of them ), and it isn't going to be deeply pre planned.
That's all I know of the rumour. But if it's true, it's going to be messy, and staff are going to have to pull together to make it happen........Which is difficult under the current CEO.
