Kuala Lumpur International Airport - Low Cost Carrier Terminal (KLIA LCC), Malaysia

KLIA's LCC terminal has been built to accommodate all of the budget airlines, including AirAsia.  It's a basic but easy terminal to use.

Before the departure lounge: There are several places to buy hot food, including a McDonalds.  There are a few shops selling the normal airport articles such as magazines, and a money changer.  Remember that you cannot change Ringgit outside of Malaysia.

Inside the departure lounge: There is a duty free shop.

Regular and Premium taxis are available outside.  Premium cost just a few Ringgit more, and I think they are worth it.

All of the terminals in KLIA have free WiFi, including the LCC.
