As it turns out, looks like I'll be flying double of what I originally thought.

BA SYD-(BKK)-LHR-FCO
BA SYD-(SIN)-LHR-BCN
QF BNE-SYD
QF BNE-SYD

All discounted Biz (assuming D class)

That makes 4 BA segs, but only 2 on QF, and none on AA. Although I'll be in the US several times this year, if I need a quick 4 segs.

Will this get me Saphire on BA, AA, QF, etc. or close to it? By Kiwi Flyer's post it appears I'd be very close on QF)

My US travel, if any wil likely be in Econ, but I usually buy Inter-Asia Biz.

I feel like a fish out of water here in oneworld, thanks for the excelent input.
