KL International Airport is surrounded by four main cities of Kuala Lumpur, Shah Alam, Seremban and Malacca. The airport is a catchment area and offers opportunities for a hive of business activities. Every effort has been made to create a homely airport with a serene environment combined with high technologies attractions. 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 was voted as the World's Best Airport (15-25 million passengers per annum) for two consecutive years, in the 2005 AETRA awards and 2006 ACI-ASQ awards.
