I'm another who will be very interested in any feedback on Air Asia. I travel to the Far East as often as I can afford, but these days the prices are getting way too much - I also have mates who live in KL that will be looking for other options to get back to UK for breaks.
I know I checked out prices with them (KL - Langkawi, KL - KK) when there last year and was impressed with prices, BUT, I need to be sure they are as reliable as the bigger airlines or going cheap could cost more.
