If you have the miles, you want to go for first class as you can hit up the A380 on Thai between BKK and HKG, then you can hit up the 777-3 SQ first class from HKG to SIN. US airways allows one stop over or one open Jaw but you can make it better by booking a roundtrip and droping the last leg to create one stopover and one openjaw (this is how you get out of booking award ticket that involve two regions). For example, SIN - BKK(stopover) - HKG - SIN. Drop the SIN segment and you can visit 2 cities in one award ticket. This award is also cheaper because US see this award as a 1 region award. If you fly first class and exit BKK you get a free 1 hour full body massage at the airport (Business class get half an hour shoulder massage). Then use your Avio to fly on CX to nearby cities. You will have to pay a small amount of YQ if you use Avio on CX
The OP doesn't list any US miles, and the UA chart for SE Asia is arguably better: 35K for C, allows one stopover and TWO open-jaws on a round trip, even on an intra-regional award. Given the short stage length of flights between HKG, SGN, PNH, BKK, KUL, SIN, I'm not sure an F redemption is going to get you all that much more than C (C is only 10K miles more than Y, BTW, which is why it's a great bargain- regional C on an Asian airline is like F+++ on an USA or European airline). And if the OP is happy flying LCCs for short flights... he might not even need that.
Also... HKG isn't in South Asia on the US chart. It's in NORTH Asia (I've used this rule to my advantage before because North America->North Asia is a lot cheaper than North America->South Asia). That increases the cost by quite a lot (60K C, 80K F).
One other thing, OP: your Virgin Atlantic miles can be used for SQ/Singapore Air flights. As can your AMEX MR.
