By Air The Kuala Lumpur International Airport (KLIA) is located 70km (43 miles) south of the city in Sepang and one of the biggest and most modern airports in Asia. Planes arrive and depart from four satellite arms, which are linked to the main terminal building via an aero train.
Nature and greenery are part of the airport in line with the "airport in the forest and forest in the airport" concept. The natural environment of the airport is transformed to functions and activities that continue to enhance nature. The abundant forest areas will be preserved and transformed into an environment park containing recreational facilities.
KLIA houses the country's national carrier Malaysia Airlines (MAS) which provide international and domestic connections to destinations on the peninsula and east Malaysia. MAS have discounted fares on some domestic connections but this means that you should prepare to travel at inconvenient times....ask for 'night tourist fares'.

Express Rail Link is the fastest way to the city centre which takes 28 minutes to get to KL Sentral Station for only RM35.
