Yes, that could be done, but would mean departing a few days earlier to complete it and arriving at my meetings in the US rather beat (like normal, I guess ). But it adds a lot of non-QF flight numbers to the trip, reducing the corp discount we receive. All bar the BNE-SYD-HKG would be CX flights. but I could get directly into SFO and avoid LAX which is attractive . Perhaps if I can't get the skybed flight SYD-LAX, I might see how much discount I lose by going SYD-HKG-SFO?? And I can take the AA codeshare and still get the 100% bonus points as a QF WP member.

Edited to add: I just checked the schedule. CX872/AA6118 departs HKG for SFO at 4:15pm. Unfortunately, there are not connections from BNE or SYD that will get me into HKG to make the SFO flight. The earliest arrival from Australia seems to be QF128 at 5:40pm . So back to the original plan I guess. Otherwise I add another day to the start and would prefer not to have to do that.
