I have seen some past posts in this forum about how QF is stopping service to Kuala Lumpur, forcing passengers to now go through SIN, as MAS 777 lamented so nicely! I don't know about Ansett, though. Frankly, if I were a passenger going from Australia to KUL, that'd be a joke! KUL and SIN are no more than 45-60 min.(?) apart by air!
Why did Qantas stop serving KUL in the first place!? Just a matter of unprofitability? I'm not so sure. But the good news is that, according to MAS 777 in his post, Malaysia Airlines is increasing service from KUL to Australian destinations.
