I am trying to book the following itinerary in Business Class for next June using a One World award: SIN-HKG-LAX-HNL-SFO-HKG-BKK-KUL.

The first six flights are confirmed in CX and AA. The problem is that I want the BKK-KUL sector in AY to get the two OW carriers required. AY in Singapore say they have seats for award travel. The regional AA reservations group (in Delhi) say they can't see them. I've even got AY res. in SIN and AA res. in Delhi to talk to each other by phone. No dice, so far.

AA are trying to get me to make this detour instead: SFO-SYD-SIN on QF, but this eats a lot of extra miles.

Any thoughts?
