airport tax is a source of government revenues. Not everyone has to pay. An airport tax is charged only to the consumer (Air Asia uses "guests"). In other words: You don't fly, you don't pay; You fly, you pay. Same in other countries; the only difference is you pay through your noses if you fly to Heathrow, Changi and elsewhere. Our airport tax is second cheapest in the region after Indonesia, and still one of the cheapest in the world.
Air Asia's ad/campaign is misleading.
|("Air Asia does not derive any profit from the airport tax collected from guests as the entire amount goes to MAHB")|
Look, NO AIRLINE IN THE WORLD derives any profit from airport taxes. That's why it's called airport tax and not airline tax.
