If you delay your trip by one day and depart on 11/01/2010 you can book:

LAX-NRT-HKG on AA for USD$1000 return. It would be AA codeshare on AA and CX (But since it is under AA code you will get full mileage).

You then purchase one seperate ticket between HKG and HKT using either miles or cash. You may save quite a lot. But do pay attention for the transit time in HKG.
