Background

The ground breaking ceremony for Kuala Lumpur International Airport (KLIA) took place on 1 June 1993^[2] when the government under Tun Dr Mahathir decided that the existing Kuala Lumpur airport, then known as Subang International Airport (now Sultan Abdul Aziz Shah Airport) could not handle future demand. The construction of the airport was done mainly by a few state owned construction companies as well as Ekovest Berhad – helmed by Tan Sri Datuk Lim Kang Hoo. It was created as part of the Multimedia Super Corridor, a grand development plan for Malaysia. The chief architect who designed the new airport terminal was the Japanese architect Kisho Kurokawa.^[3]

Upon KLIA's completion, Subang Airport's Terminal 1 building was demolished. Malaysia Airports agreed to redevelop the remaining Terminal 3 to create a specialist airport for turboprop and charter planes surrounded by a residential area and a business park.^[4] The IATA airport code KUL was transferred from Subang Airport, which currently handles only turboprop aircraft, general aviation and military aircraft.

Current site

The airport's site spans 100 square kilometres (39 sq mi) ^2[5] of former agricultural land and is one of the world's largest airport sites. An ambitious three-phase development plan anticipates KLIA to have three runways and two terminals each with two satellite terminals.^[6] Phase One involved the construction of the main terminal and one satellite terminal, giving a capacity of 25 million passengers, and two full service runways. The Phase One airport had sixty contact piers, twenty remote parking bays with eighty aircraft parking positions, four maintenance hangars and fire stations. Phase Two, designed to increase capacity to 35 million passengers per year is largely complete. Phase Three is anticipated to increase capacity to 100 million passengers per year.^[6]

Grand opening

Kuala Lumpur International Airport was officially inaugurated by the tenth Yang di-Pertuan Agong, Tuanku Ja'afar of Negeri Sembilan, on 27 June 1998 at 20:30 MST. The first domestic arrival was Malaysia Airlines flight MH1263 from Kuantan at 07:10 MST. The first international arrival was Malaysia Airlines flight MH188 from Malé at 07:30 MST. The first domestic departure was Malaysia Airlines flight MH1432 to Langkawi at 07:20 MST; the first international departure was Malaysia Airlines flight MH84 to Beijing at 09:00 MST.^[7]

Inauguration

The inauguration of the airport was marked with numerous problems. The aerobridge and bay allocation systems broke down, with queues building up throughout the airport and the baggage handling breaking down. Bags were lost, and there were waits of over five to seven hours.^[8] Most of these issues were remedied eventually, though the baggage handling system was plagued with problems until it was put up for a complete replacement tender in 2007.

The airport suffered greatly reduced traffic with the general reduction in economic activity brought about by the 1997 Asian financial crisis, September 11 attacks, SARS, bird flu epidemic (Avian flu), the financial crisis of 2007–2008, the 2009 swine flu pandemic and the COVID-19 pandemic. The airport is also largely overshadowed by the more internationally renowned Changi Airport located approximately 300 kilometres (190 mi) to the southeast in Singapore, especially in regards to connecting flights by various airlines or Malaysians especially living in the southern parts of the country (e.g. Johor) preferring to travel via Changi rather than at KLIA.

The first year of opening immediately saw reduction of passenger numbers as some airlines, including All Nippon Airways (resumed on 1 September 2015), British Airways (reinstated on 28 May 2015 until 28 March 2021^[9]), Lufthansa (resumed between 28 March 2004^[10] until 28 February 2016)^[11] and Northwest Airlines, terminated their loss-making services to KLIA. KLIA's first full year of operations in 1999, in its Phase One manifestation (capacity of 25 million passengers per year), saw only 13.2 million passengers.^[12] Passenger numbers eventually increased to 21.1 million in 2004 and 47 million in 2013^[13] — though short of the originally estimated 25 million passengers per year by 2003.

Rebranding

On 9 February 2023, transport minister Anthony Loke Siew Fook announce that the government and MAHB had agreed to rebrand KLIA and klia2 to KLIA Terminal 1 and KLIA Terminal 2 respectively.^[14] The costs associated with the rebranding will be fully borne by MAHB.^[15]

KLIA Terminal 1

KL City Air Terminal

KL City Air Terminal, sometimes known as Kuala Lumpur City Air Terminal or KL CAT, located at KL Sentral, is a virtual extension of KL International Airport where city check-in services are provided. KL City Air Terminal is recognised by the International Air Transport Association (IATA) and carries the IATA designation XKL. Currently there are only three airlines providing city check-in services: Cathay Pacific, Malaysia Airlines and Malindo Air.^[32]

KLIA Terminal 2 (Formerly known as KLIA2)

Built at approximately RM4 billion, it is the largest purpose-built terminal optimised for low-cost carriers in response to the exponential growth of low-cost travel in the region. It was built to replace the previous Low Cost Carrier Terminal (LCCT). KLIA T2 began its operations on 2 May 2014, and all flight operations at LCCT were moved to KLIA T2 by 9 May 2014.^[33][34]

As part of its development, a third runway (Runway 15/33) and a new air traffic control tower (Tower West) were built to support its operation. KLIA T2 has an initial capacity of 45 million passengers per year. The terminal has a built-up area of 257,845 sqm with 68 departure gates, 10 remote stands, 80 aerobridges, includes a retail space of 32,000 sqm to accommodate a total of 220 retail outlets.^[35] The main terminal building of KLIA T2 is connected with its satellite piers with a skybridge, making it the first airport in Asia with such facility.^[36] KLIA T2 is certified with Leadership in Energy & Environmental Design (LEED).

Check-in counters are divided into 8 rows located in 4 islands, each row identified by the letters S – Z. Boarding gates are located in 5 piers, indicated by the letters J and K for domestic flights, and L, P and Q for international flights. Piers J, K and L are connected directly to the main terminal building, while Piers P and Q are accessible via the skybridge. Piers K and L are physically the same pier and share the same gates, but with waiting lounges on different levels (Level 1A for K and Level 2 for L). For international flights, the access door from Pier K is sealed off, while for domestic flights, the access door from Pier L is sealed off instead.^[37][38]

At present, inter-terminal connection is provided on the landside at Gateway@klia2 complex and there are provisions for future airside inter-terminal connection.^[39]

Former Low Cost Carrier Terminal (LCCT)

The now defunct 36,000 square metres (390,000 sq ft) low cost carrier terminal (LCCT) was opened at Kuala Lumpur International Airport on 23 March 2006 to cater for the growing number of users of low-cost airlines, especially the passengers of Malaysia's "no-frills" airline AirAsia. The terminal was designed and built in accordance to the low cost carrier business model, with limited terminal amenities. As requested by the low-cost airlines, the terminal did not provide aerobridges, nor were there transfer facilities, rail connections, and the other facilities provided in a fully fledged terminal. LCCT was located within the Air Support Zone; it ceased operations on 9 May 2014, and all low-cost carrier flights subsequently operated out of KLIA T2.^[43]

Inter-terminal transportation

The Aerotrain, currently out of service for repairs, is an automated people mover (APM) that connects the airside of KLIA Main Terminal Building (MTB) and the Satellite Building. Each 250-person capacity train can transport 3,000 passengers per hour in each direction at up to 56 km/h (35 mph). These three-car driverless trains run on elevated rail and under the taxiways. The journey takes under two minutes. The Aerotrain operates between three and five-minute intervals between terminal. Automatic train controls manage the operation of the entire Aerotrain system, controlling the speeds, headways, stops and door openings in stations, and integrating functions that enhance the reliability and performance of the system.^[177]

No airside connection currently exists between the Main Terminal Building and Terminal 2; connecting passengers must clear Malaysian immigration and customs checks before taking a landside transportation option (Express Rail Link, bus or taxi).

External connections

Plans

With the slight modification of the masterplan, the future Terminal 2's satellite terminal will be combined into one satellite terminal. The expansion of Terminal 2's satellite terminal will be exactly the same as Terminal 1's (the current Main Terminal) satellite terminal, where initially the satellite terminal will have four arms, and another four arms when the terminal reached its capacity. There is sufficient land and capacity to develop facilities to handle up to 97.5 million passengers a year, four runways by 2020 and two mega-terminals, each linked with satellite terminals.^[6]

A380 upgrades

The operator of Kuala Lumpur International Airport, Malaysia Airports Holding Berhad, had spent about RM135 million (approx) to upgrade facilities at the KL International Airport (KLIA) in Sepang to accommodate the Airbus A380. KLIA is the only airport in Malaysia that accommodate the landing and take off of the A380. Upgrading works started on 3 April 2006, and was completed by 28 May 2007. Works include the provision of shoulders on both sides of the two existing runways of 15 meters as well as the taxiways, building additional aerobridges at the three departure halls, namely C17, C27 and C37, and enhancing the mezzanine lounges for upper deck passengers of the aircraft at the departure halls. Emirates is the only current operator of the Airbus A380 to Kuala Lumpur; its services commenced on 1 January 2012.^[178] Malaysia Airlines started its A380 services from Kuala Lumpur to London on 1 July 2012 before retiring the aircraft type at the end of 2018.^[179]
