Kuala Lumpur International Airport (KLIA) is the largest and busiest airport in Malaysia
KLIA is served by the toll-free KLIA Expressway, an 11-kilometre direct road from the KLIA Interchange of the ELITE Expressway, which connects to major townships in Klang Valley and further to Peninsular Malaysia's west coast states, reaching the border with Thailand and Singapore. The airport features two air traffic control towers: Tower East, the original tower at 130 metres tall, and Tower West, the tallest air traffic control tower in the world at 133.8 metres. KLIA is one of the first Asia Pacific airports to become fully Bar Coded Boarding Pass capable. It also boasts state-of-the-art facilities, modern architecture inspired by traditional Malay elements, and a unique "forest" theme with an entire section of rainforest transplanted inside the Satellite Building, earning the United Nations' Green Globe 21 certification annually since 2004.
KLIA Terminal 1 (also known as Kuala Lumpur International Airport Terminal 1) is Malaysia's main international airport and the leading aviation hub in Asia. It comprises three main buildings: the Main Terminal Building (MTB), the Contact Pier, and the Satellite Building. The airport is currently undergoing expansions and upgrades to accommodate growing passenger numbers and technological advancements, ensuring its competitiveness and world-class status. KLIA Terminal 1 has won multiple awards for excellence, including the World's Best Airport at the Skytrax World Airport Awards.
KLIA is operated by Malaysia Airports (MAHB) Sepang Sdn Bhd and serves as the major hub for Malaysia Airlines, MASkargo, AirAsia, AirAsia X, Batik Air, UPS Airlines, and Gading Sari. AirAsia is the dominant air carrier in Malaysia, serving 14,583 low-cost connections with a 34% share of flights. The groundbreaking ceremony for KLIA took place on June 1, 1993, as the existing Kuala Lumpur airport (then Subang International Airport) could not handle future demand. The construction was undertaken by several state-owned companies, including Ekovest Berhad, as part of the Multimedia Super Corridor development plan for Malaysia.
