I tend to agree. Given the new joint venture with Virgin Atlantic, I can't see VA withdrawing from HKG completely. But I could see them cut back from 2 to 1 daily flights to HKG.I can see a world where MEL-HKG disappears in favour of BNE-HND
I suppose 4x weekly SYD-HKG and 3x weekly MEL-HKG could also be possible, but I think they would favour daily service from one port. And that one port is more likely to be SYD than MEL, given the only reason they started serving HKG from MEL in the first place was due to the curfew in SYD - something that is no longer a problem as they have better slots in HKG now.
