Hi Samba
It is a good idea to give more info if you require useful reply.
Here's my suggestions:
Look for special offers - Due to SARS there are some discounts available. One example from BA (using Asia Miles) is below - straight from Asia Miles web site.
Fly British Airways World Traveller Plus for 40% FEWER Asia Miles
Now you can enjoy the comfort of British Airways World Traveller Plus -- with a wider seat and seven inches of extra leg room -- at a special discount of 40% fewer Asia Miles:
Fly British Airways World Traveller Plus Normal redemption 40% fewer Asia Miles
Round-trip between Hong Kong/Beijing - London 72,000 Asia Miles 43,200 Asia Miles
Round-trip between Singapore - Sydney/Melbourne 54,000 Asia Miles 32,400 Asia Miles
If you have an AMEX card, you can transfer points at the rate of 1 Asia miles for two AMEX points. I think Diners also does the same.
If you stay in a partner hotel (anywhere in the world) you will get 500 points per stay. You need just 3 stays ; - ) Also look at car hire etc.
If you live in HK there's a whole load of mobile phone and other offers. Visit the Asia Miles site.
