I would agree with rodondo 4 in pumping for Malaysian for all the reasons mentioned by him. The savings can be considerable for virtually the same sort of service you get with other airlines.
Plus, if you are a fan of quiet airports, then KLIA is the place
(last time I was there at 9 AM, some gates were proudly displaying signs like "THE NEXT FLIGHT FROM THIS GATE IS THE 9 PM SERVICE TO CAIRNS!!!".
Jokes apart, I have taken about 6 flights on Malaysian via Kualalumpur over the past two years and the service has been consistently good. The aircraft and airporft are relatively news, the service is efficient and on my first trip there I landed in Kuala Lumpur the day after they airline switched their reservation systems and even then they handled it efficiently (a similar switch by US airways some years back created headlines for the chaos caused all over!). Also most of the full frills you expect in airlines like Singapore and Emirates are availble in Malayisan also. All my special meals requests have beeb attended to, Also the cabin crew actually seem to enjoy their work and show it, wheich is sometimes a complaint made against its more famous neighbour where there ius a complaint that service can get a little robot like!
Cheers
