Hi Everyone, I need your help/expertise. This is only the second time I'm booking an award ticket and I'm in over my head.

I'm trying to book two business tickets from SFO/LAX that will include London, Singapore and Sydney and preferably Hong Kong as stops. Stopover about two weeks at each location, no particular order or airline preference.

Using ba.com, I saw that next September a BA flight from London to Sydney stopping over in SIN would cost 100K miles and about $722 in taxes. I was hoping to book a LAX to London flight on BA as part of that same 100K miles fee. The last flight I booked was on CX from SFO to Asia and back for 100K miles total in business.

I guess I'm not really understanding how this works. Is there any way to book a RT from SFO to those cities (London, Sydney, etc) for less than 200K miles?

Thanks in advance.
