QFBoy, what I mean is that certain carriers have rights between asian ports such as BKK-SIN and BKK-HKG and you can often find fairly cheap business class deals for these trips all around 1000miles. CX does a few tags BKK-SIN, and AY does BKK-HKG (or did last time I looked). These can be bought from the airlines websites (select thailand...) at the Thai rate (NOTE, do not book from the other end, eg: SIN-BKK or HKG-BKK) - these will be more expensive. I found that you could get around $A400 for BKK-SIN and similar BKK-HKG (noting that flights don't fly every day of the week and thinks like that).
It never quite worked out for me time wise to take advantage of this deal, but if one wanted a quick 120-200 SC's at a reasonable price not too far from home, it might be an option.
