The recent promotion by MAS, the local and first airlines in Malaysia has been countered by Air Asia (the budget airlines from Malaysia). While Mas claimed that they offer zero fare to passenger (still do not except really zero fare, you need to pay for the airport tax and fuel surcharge). I guess it is not the cheapest if compare to Air Asia, because (I think) Air Asia is based in the Low Cost Carrier Terminal while MAS takes off from KLIA. Is the airport tax the same? A few days later Air Asia came out with their sub-zero fare....what is it????Check out the advertisement in local newspaper. or log into Air Asia's website.
