Looks like HKG is hotting up as a special destination - availability Feb - March 2012

Update:

Called Singapore Airlines last night and they made a special call to Thai, who (after some prodding by the helpful SQ consultant) released the fare. So all good, everything is booked and paid.

However, the fuel surcharge really does bother me (although there is little one can do about these compulsary taxes is there?).

For instance, my SYD-BKK flight had the following charges:

Tax: AU = 63.00 / WY = 34.00 / YQ 164.00
Total: $261.00 SGD

All up, we paid about $1700 SGD ($1288 AUD) for the following

2 x J SYD-BKK (+90,000 points)
2 x J BKK - DPS (+40,000 points)
3 x Y BNE - BKK (+105,000 points)
3 x Y BKK - DPS (+37,500 points)

...which seems outragous. Oh, and keep in mind that because we booked one way (we're flying Virgin back to Australia from Bali), we were not allowed a stopover in BKK, so we paid 45,000ea in J for SYD-BKK + 20,000ea in J for BKK-DPS. So instead of getting the nice 45,000 points for "South Asia 1", we were slugged the additional fee for the additional "South Asia 1 > South Asia 1" ticket.

Hardly seems worth it in the end, but after the hassle we went through to actually make the booking we just went with it...

There is an "official update" on FT stating that Diamond Club will not be merged into M&M in 2011, Miles+Cash is "here to stay" and there are no changes planned to redemption rates. (link)
