Intra-Asia MH flights are usually very cheap, as long as you are not originating or
ending in KUL. I have found, for example that MH BKK-KUL-CGK is half the price
of any non-LCC carrier in J class. So be sure to look for something like PEK-KUL-SIN-KUL-PEK, with a stopover on one of the connections.
