I am planning to leave SVG on BA747 on Aug 27th that is the only fixed bit. Returning around 6/7th Sept.
I came up with a few options I came up with on the outbound, but none of them go via PEK:
I have BA33 going to KUL (would be nice to try F on 789), followed by BA4564 to HKG with a day in HKG and BA4137 to SYD.
Another option I came up with was BA27 to HKG, followed by a day in the city and CX to PER and QF to SYD.
Looking forward to some suggestions :-)
