History

Background

The groundbreaking ceremony for Kuala Lumpur International Airport (KLIA) took place on 1 June 1993 when the government under Mahathir Mohamad 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.

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. 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 ² 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. 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 60 contact piers, 20 remote parking bays with 80 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.

Inauguration

Kuala Lumpur International Airport was officially inaugurated by the tenth Yang di-Pertuan Agong, Tuanku Ja'afar of Negeri Sembilan, on 27 June 1998, shortly before the 1998 Commonwealth Games.

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. 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 2008 financial crisis, 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 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), Lufthansa (resumed between 28 March 2004 until 28 February 2016) discontinued their flights. Qantas moved their Sydney-Kuala Lumpur route to its low-cost subsidiary Jetstar, which continued to operate the route until 2008. Aeroflot terminated their Moscow-Kuala Lumpur via Singapore route in 2001, although there had been discussions about Aeroflot resuming the Kuala Lumpur route, no progress was made, and Northwest Airlines terminated their loss-making route from Osaka to Kuala Lumpur in 2001. 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. Passenger numbers eventually increased to 21.1 million in 2004 and 47 million in 2013 — though short of the originally estimated 25 million passengers per year by 2003.

Rebranding

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

Runways

Kuala Lumpur International Airport has three parallel runways (14L/32R; 14R/32L; 15/33), which all three of which are over long and wide. The length of Runway 14L/32R is , runway 14R/32L is , while runway 15/33 is . Each runways had at least nine taxiways exits ranging from 2 minutes to 11 minutes.

The current three runway system is capable of handling 78 landings per hour and was expected to increase to 108 landings per hour once upgrading of the Kuala Lumpur Flight Information Region had been completed in 2019. The airport has CAT II Precision Landing ILS (runways 14L/32R and 14R/32L) to guide landing aircraft safely under all weather conditions with visibility as low as 350 metres (1,150 ft) whilst runway 15/33 has CAT I Precision Landing ILS that guide safe landings under all situations with lowest possible visibility at 900 metres (2 953 ft). These runways operate on different departure/arrival modes according to the air traffic requirements.

Operations and infrastructure

Kuala Lumpur International Airport features a number of modern design features that assist in the efficient operation of the airport. It is one of the first Asia Pacific airports to become 100% Bar Coded Boarding Pass capable. Malaysia Airlines; AirAsia; MASkargo, a cargo airline; and Malaysia Airports, the Malaysian Airports operator and manager; are headquartered on the property of KLIA. Malaysia Airlines also operates its Flight Management Building at KLIA.

Air traffic control tower

There are two air traffic control towers at Kuala Lumpur International Airport: the two main control towers (Tower East and Tower West) and the apron control tower. Tower East is the original control tower which stands since the start, towering at 130 metres tall and control the traffic of both initial two runways. Tower West is 133.8 metres tall and is the tallest air traffic control tower in the world, followed by Suvarnabhumi Airport's control tower and Tower East during its inauguration which now being beaten by King Abdulaziz International Airport which possess a 136 metres tall air traffic control tower. Both shaped like an Olympic torch, it houses the air traffic control systems and radar equipment.

The 55-metre apron control tower is responsible for providing Air Traffic Service to aircraft and vehicle movement in the northern and southern parts of the Satellite Terminal building and the cargo apron areas.

Baggage handling system

The airport's baggage handling system (BHS) features baggage common check-in at any of the 216 counters on a 24-hour basis and incorporates automatic bar-code sorting control, 4 level in-line baggage security screening and high speed conveyor belts.

The BHS was built by Toyo Kanetsu with lots of new mechanism such as Belt Carry Sorter, Triplanar, Hinged Diverter, Horizontal Sliding Belt Diverter, and FOD (foreign object debris) Detection System. In 2006, a contract to extend the system from the satellite building to the ERL (Express Rail Link) platform in the Main Terminal Building was awarded to Siemens. The new system from Siemens will transport baggage between the two terminals at speeds of up to 36 km per hour, compared to the previous rate of 7.2 km per hour. The new system uses a high-speed tray conveyor system in which bags are placed on individual trays for better control and tracking at high speed compared to conventional belt conveyors enables the baggage to be checked-out in KL Sentral once the operator of KLIA Express, ERL Berhad introduce the new facility.

Some of the facilities of the baggage handling system in Terminal 1 include:
*Eight short-term car park baggage check-in counters
*Eight bus and train stations baggage check-in counters
*Three stage baggage security screening system
*Early check-in baggage storage (1,200 bags capacity)
*17 baggage reclaim carousels together with LCCT
*33 km total length of conveyor belts
*Part of the belts travel through a 1.1 km tunnel from the Main Terminal Building to the Satellite Building

Meanwhile, in Terminal 2, the baggage handling system being implemented by BCS Group from Norway and upgraded by Daifuku Airport Technologies From Japan until its opening in May 2014, costing RM 60 million. The BHS in Terminal 2 is as follows:
* 128 check-ins
* Over 10km in aggregate length for over 1,200 conveyors
* Over 2km in aggregate length for 21 carousels
* CCTV system for the complete baggage system
* Two High speed tilt tray sorters
* 14 inline screening X-ray machines on the conventional baggage system plus 5 for the out of gauge lines
* 250 barcode readers
* EBS infrastructure for early bags

Several companies handle the baggage systems in KLIA. For the homebase airlines, Malaysia Airlines operates the BHS through AeroDarat Services, AirAsia uses Ground Team Red, and Malindo has their own baggage crews. There are also two more baggage handlers operate under Kuala Lumpur Airport System (KLAS) which are Pos Aviation and ProSky Services.

IATA had agreed to facilitate the usage of RFID tags between KLIA and Hong Kong International Airport after the launch of the world's smallest multiband RFID chip in Kuala Lumpur. KLIA will be the second airport to use RFID.
The RFID baggage tagging trial between KLIA and Hong Kong International Airport is completed. Baggage tags are being issued at both Malaysia Airlines and Cathay Pacific check-in counters. The trial was delayed due to problems obtaining printers. Furthermore, KLIA is now awaiting reports from IATA which scheduled to be released first quarter of 2008.

In 2017, there was a mishap of baggage handling which caused 50 flights delays and affected 1500 passengers which later managed to be solved. The increasing passengers traffics and non-optimized system due to never being replaced gave a signal for MAHB to implement BHS upgrade in 2019 which predictably will cost RM 500-600 million. There are four Bursa Malaysia company with joining in force with six multinational company were competing for the tender. The project was being given to T7 Kemuncak Sdn. Bhd. with the joint venture with Siemens Logistics. The new BHS will provide a boost of extra 2500 bag positions with the new system called VarioTray, which is a high-speed conveyor system connected between the Main Terminal Building and Satellite A, will enable bags to be transferred swiftly and securely between the two buildings.

Fire and rescue

KLIA's Airport Fire and Rescue Services (AFRS) rated Category 10 (can handle emergencies involving huge jumbo jets such as Airbus A380, Antonov An-225 and Boeing 747-8) are provided to cope with aircraft accidents. This is important as KLIA itself is categorised as a National Vital Installation Priority 1, representing facilities of the highest importance to national security and the function of government.

There are three fire stations at the airport near each runway, fully equipped with fire and emergency rescue equipment. There are total of 10 Ultra Large Foam Tender, Ziegler 8-(8x8) vehicles costing RM 3.8 million each.

Air cargo

The KLIA Advance Cargo Center (ACC) covers of land and can handle one million tonnes of cargo per annum, with the capability to expand to 3 million tonnes/year. The center is designed as an integrated transshipment hub within a Free Commercial Zone. Fueled by high economic growth in the Southeast Asian countries and China, the airport handled 677,000 tonnes of air cargo in 2006, a 5.9% growth over the 2005 fiscal year.

To handle the cargo efficiently, the ACC is equipped with the following:

*Container Storage System (CSS) – over 2,200 storage positions to accommodate various ULDs with 5ETVs
*Automated Storage and Retrieval System (ASRS) – 12 units Stacker Cranes for 6,500 storage bins
*60 units of Automated Electrified Monorail linked to 10 units of interfloor hoists
*28 units Airside Interface Deck
*Two units bypass Conveyor system dedicated for SLAC ULD
*Over 100 Breakdown and buildup workstations
*Over 100 truck docks
*13 units fully automated transfer vehicles
*Two units 20 tons Bridge cranes
*Odd-sizes storage space (OVS)
*Computerised Truck dock management system
*Over 14,000 sqm of Unit Loading Devices Storage Yard
*Weighing scales – Automated weighing scale interface with material handling system, maximum capacity 20,000kgs
*ULD and large skid X-ray machines
*24 hours warehouse surveillance with close to 200 CCTVs

Applying added information technologies, the main operator of the center, MASkargo with joint venture with Unisys, introduced various artificial intelligence systems to handle cargo such as KLIA Community System (KLIACS), optimize load utilization, routing and inventory for air cargo, ground handlers and freight forwarders. the authority also pioneered the DagangNET System, allowing users to conduct trade declarations and apply for permits over the internet and speeding the approval process by controlling authorities. These systems will be linked the Total Airport Management System.

According to MAHB, the cargo movement of KLIA is 656,762 tonnes in 2023.

Animal hotel

The animal hotel is operated by Malaysia Airlines's cargo arm, MASkargo. The hotel operates 24 hours and manages all imports, exports and stop-over transhipments that are related to animals, and offers a pets stay-in program where owners can leave their pets to in the hotel while they are away for vacations mainly at Kuala Lumpur Animal Quarantine Station (KLAQS). At least 500 consignments of livestock being handled per day at the animal hotel.

Aircraft maintenance

There are four hangars housing facilities to provide aircraft maintenance provided by Malaysia Airlines and Kuala Lumpur Airport Service (KLAS) suitable for Maintenance, Repair and Overhaul (MRO) activities. The airport also has a hangar which is purposely built for the Airbus A380, the first in Southeast Asia. The construction of the hangar was completed in 2007. Asian Digital Engineering, the MRO arm of AirAsia has launched a new 14-line hangar that covers 35,300 sq m on an 8.2ha site that features dedicated workshops, including a composite workshop, sheet metal and machine workshop, upholstery workshop, cabin interior repair workshop and a 3D printing lab for aircraft livery.

Meteorological services

The Aeronautical Meteorological Station (AMS) is located near Runway 14R-32L which provides weather information for the aviation community in compliance with International Civil Aviation Organization standards. The AMS houses a Meteorological Data Processing System (MDPS) for weather data collection, processing, storage and analytical needs. AMS constantly make weather observations using radiosonde instrument to measure atmospheric profiles such as wind speed, wind direction, pressure, temperature and humidity at every level up to an altitude of about 30 kilometres before issuing aerodrome warnings on adverse weather for protection of aerodrome facilities and aircraft on the ground.

Terminals

Kuala Lumpur International Airport comprises two main terminals: the original terminal, Terminal 1, previously known simply as "KLIA"; and the newer Terminal 2 (formerly KLIA2). Terminal 1 was designed by Japanese architect Kisho Kurokawa, who also designed the Domestic Terminal (T2) at Nursultan Nazarbayev International Airport, with an emphasis of natural lighting within the airport complex. Spanning 38.4m along a grid pattern allowing for future expansions, the abstract symbolic architecture by the late Kisho Kurokawa encompasses the Islamic geometry and cutting-edge technology with the tropical rainforest in mind.

KLIA Terminal 1

Main Terminal Building

The KLIA Main Terminal Building (MTB) now also referred to as KLIA Main is located in between the two runways. The floor area of the terminal covers and the building consists of 39 square roof units, which enables future expansion of the building. There are a total of 216 check-in counters, located in 6 different islands, identified by the letters A – M (excluding I). Multi check-in services are available, designed for the use of all passengers arriving, departing or in transit. Self check in facilities are available in this airport since 2007, and KLM was the first airline to use the Common-use self-service kiosks.
The contact pier is an extension of the main terminal building with gates marked with prefix ''A'' and ''B'' for domestic departures, ''G'' and ''H'' for international flights. The gate allocation is based on operational requirements, although it has been observed that Malaysia Airlines has been operating most of its operations out from the contact pier.

Satellite Terminal A

The satellite building accommodates international flights departing and arriving at KLIA T1. Passengers taking flights parked at the satellite terminal are transported by bus from the main terminal; as of March 2023, the Aerotrain that connects this building with the main terminal has been suspended for repairs and rolling stock replacement and is expected to be operational in the second quarter of 2025.

There is a wide array of duty-free shops and prestige brand boutiques in the satellite building. This includes international brands such as Burberry, Harrods, Montblanc, Salvatore Ferragamo, and Hermes. Among all international labels available within the terminal, some boutiques such as Harrods are only available in the airport. A number of restaurants and international airlines' lounges are available as well as an Airside Transit Hotel.

Within the terminal, wireless internet (Wi-Fi) is provided free of charge. The terminal also has prayer rooms, showers and massage service. Various lounge areas are provided, some including children's play areas and movie lounge, broadcasting movie and sport channels. The terminal also features a natural rainforest in the middle of the terminal, exhibiting the Malaysian rainforests.

Under Malaysia Airports Berhad retail optimisation plan, the retail space in satellite terminal A will be further optimised to increase its revenue derived from commercial space rental and a percentage of sale receipts to 50% by year 2010 which currently stands at 35%. Some notable improvements that will be seen after the refurbishments will be the Jungle Boardwalk which will be the first of its kind in the world and larger mezzanine floor to accommodate F&B outlets and viewing galleries.

The gates in Satellite Terminal A have the prefix ''C''. The Satellite A terminal has 27 boarding gates altogether.

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 two airlines providing city check-in services: Malaysia Airlines and Batik Air Malaysia.

KLIA Terminal 2 (formerly known as KLIA2)

Built at a cost of approximately RM4 billion, it is the largest purpose-built terminal optimised for low-cost carriers, like AirAsia 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.

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. 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. 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.

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

Gateway@klia2

Gateway@klia2 is an integrated shopping complex that is connected to the main KLIA T2 terminal building. It has a 350,000 square feet of net lettable space spanning over four levels. The transport hub at Gateway@klia2 links klia2 to the KLIA Ekspres and KLIA Transit service, with allotted pick-up and drop-off areas for coaches, taxis, rented vehicles and private transportation.

Gateway@klia2 hosts an 8-storey car park that directly adjoins KLIA T2. There are 6,000 covered parking lots at Blocks A and B and another 5,500 lots at car park D (KLIA2 parking rate). Shuttle buses are available to take the public from the car park D to the terminal. The first capsule transit hotel in Asia, the Capsule by Container Hotel, is also located at Gateway@klia2. Gateway@klia2 is managed by WCT Holdings Berhad.

Former Low Cost Carrier Terminal (LCCT)

The now defunct 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.

Future Expansion Plans

Malaysia Airports Holdings Berhad (MAHB) has announced plans to expand the Kuala Lumpur International Airport to accommodate the increasing number of air travelers. Transport Minister, Anthony Loke Siew Fook stated that the proposal includes increasing the capacity of KLIA Terminal 1 from 30 million passengers per annum (mppa) to 59 mppa and KLIA Terminal 2 from 45 mppa to 67 mppa. The expansion plan also considers constructing a fourth runway and a new Terminal 3 in the future.

In addition to the long-term plans, short-term measures have been introduced to improve the passenger experience, such as the installation of self-check-in kiosks and the addition of 20 new immigration autogates. Furthermore, MAHB plans to build a Private Premium Terminal designed for passengers seeking premium services, offering expedited immigration and customs processes and accommodating up to 100 users at a time. This project is currently in the planning stage and is expected to begin in 2025.

MAHB also aims to establish a Hajj and Umrah Terminal with a capacity of five mppa, specifically catering to Muslim pilgrims traveling to Saudi Arabia. This terminal would enable Saudi Arabia's immigration pre-clearance procedures to be conducted at KLIA, reducing waiting times at King Abdulaziz International Airport in Jeddah. However, this development is contingent on approval from the Saudi Arabian government.

Ground transportation

Inter-terminal transportation

The AeroTrain (KLIA), Aerotrain, currently out of service for repairs, is an People mover, 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.

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).

Expansion and developments

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.

On 12 December 2024, Transport Minister, Anthony Loke Siew Fook announced that plans to expand KLIA are in the pipeline to cater for the increasing flight passengers. The proposal includes increasing the capacity of T1 from 30 million passengers per annum to 59 million and T2 from 45 million to 67 million. A fourth runway and a new terminal, T3 are also in consideration.

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. 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.
