# Sultan Abdul Aziz Shah Airport

Sultan Abdul Aziz Shah Airport (IATA: SZB, ICAO: WMSA) also known as Subang SkyPark, — formerly Subang International Airport/Kuala Lumpur International Airport, often called Subang Airport — is an airport located in Subang, Petaling District, Selangor, Malaysia. Serving as the main airport for Kuala Lumpur from 1965 to 1998, replacing the former Sungai Besi Airport, before being succeeded by the newer Kuala Lumpur International Airport in Sepang.
The airport serves as a central hub for regional and charter carriers, including Firefly, Berjaya Air, MHS Aviation and Weststar Aviation. It continues to attract travelers from Kuala Lumpur due to its proximity to the city center and convenient location in the Klang Valley.
As of 2024, commercial jet operations have returned to Sultan Abdul Aziz Shah Airport, linking Subang to several regional destinations. It remains an important center for general aviation and domestic flights, with ongoing plans for further development. The airport is also aiming to become a leading center for aircraft Maintenance, Repair and Overhaul (MRO) services, as well as other aerospace activities in the region.

## Background and Development
### Planning and Construction

The construction of Sultan Abdul Aziz Shah Airport, initially named Subang International Airport, commenced in 1961 and was completed in 1965 at a cost of approximately RM52 million (then equivalent to $64 million). Built on 535 hectares of land, the airport was part of a larger government initiative to establish a modern international gateway for Malaysia. The decision was made in 1960, recognising the need for a new, larger airport to replace the aging Sungai Besi Airport.
Designed by architects Kington Loo and C.H.R. Bailey of the Booty Edwards Architectural practice, the airport featured an innovative and unique architectural design. The iconic floating concrete shell roof, supported by mushroom-shaped columns, became one of its defining features. Additionally, a circular ramp, inspired by the penguin pavilion at London Zoo by Berthold Lubetkin, provided a distinctive visual focal point, contributing to the airport's architectural identity.
On 30 August 1965, the airport officially opened its doors, becoming Malaysia's primary international gateway. The inauguration ceremony was attended by more than 1,500 guests and was officiated by the Yang di-Pertuan Agong, Tuanku Syed Putra ibni Almarhum Syed Hassan Jamalullail. The first commercial flight to land at the airport, a Malaysian Airways Silver Kris (De Havilland Comet) from Singapore, arrived at 8:15 a.m. on the following Wednesday.
The airport's runway, measuring (3,780 m (12,401 ft 7 in) long, 45 m (147 ft 8 in) wide – runway 15 – 33), was the longest in Southeast Asia at the time, making it capable of handling large, long-haul aircraft. With this infrastructure, Subang International Airport replaced the Sungai Besi Airport (also known as Sempang Airport), which had served as the main airport for Kuala Lumpur before its closure.

### Growth and Expansion

After its inauguration in 1965, Subang International Airport quickly became Malaysia's primary aviation hub, handling both international and domestic flights. During the 1970s and 1980s, the airport underwent several expansions to meet the growing demand for air travel in the country.
One of the most significant renovations began in 1980, with the goal of modernising and expanding the airport. This expansion resulted in the removal of several original design features, including the distinctive circular ramp and sections of the floating roof. These changes were implemented to accommodate the growing number of passengers and meet increasing operational demands.
The renovation progressed slowly at first, causing frustration for Prime Minister Datuk Seri Dr. Mahathir Mohamad. To expedite the process, he instructed that Terminal 2 be extended to handle all airport operations, allowing Terminal 1 to undergo complete renovations.
The upgraded Terminal 1, unveiled on June 1, 1983, was celebrated for its "ultra-modern" features, which were considered groundbreaking at the time. These included a baggage trolley conveyor, nose-in aircraft parking apron, 12 aerobridges, duty-free shops and walkalators. The introduction of aerobridges marked a major improvement, eliminating the need for passengers to board aircraft via stairs, though it also ended the tradition of waving off passengers from the viewing gallery. This gallery was eventually closed off for security reasons, with passengers now being seen off behind double-glazed glass.
On 1 December 1989, Terminal 2 took over all domestic flights. It continued to handle domestic services until 16 December 1993, when Terminal 3 assumed responsibility.
By 1993, Subang Airport had three terminals:
* Terminal 1: Dedicated to international flights.
* Terminal 2: Used primarily for the Kuala Lumpur-Singapore shuttle flights operated by Malaysia Airlines and Singapore Airlines.
* Terminal 3: Focused on domestic flights, improving the efficiency of both domestic and international operations.
The airport’s growth continued through the 1990s, with Subang handling a record 15.8 million passengers by the end of 1997, the year before its operations were transferred to Kuala Lumpur International Airport (KLIA). In recognition of the airport's significance, it was renamed Sultan Abdul Aziz Shah Airport in 1996, after the then Sultan of Selangor, Sultan Salahuddin Abdul Aziz Shah Al-Haj, who also served as the 11th Yang di-Pertuan Agong.
Despite these advancements, the airport faced operational challenges as it continued to handle a rising volume of air traffic. In particular, Subang was affected by two major fires in the 1990s that disrupted its operations. The first fire occurred in April 1992, resulting in the deaths of three security guards from the Civil Aviation Department and causing significant damage to 29 duty-free shops. The loss was estimated between RM20 million and RM30 million. Investigations revealed that the fire was caused by faulty wiring carried out by unqualified contractors. Another fire broke out in the airport's control tower in October 1992, destroying critical radar systems, computers and other equipment worth over RM2 million. A former assistant air traffic controller was later convicted for causing the fire and sentenced to 10 years in prison.
As Subang's capacity continued to be stretched, the Malaysian government recognised the need for a new, larger airport to accommodate future growth. This led to the development of Kuala Lumpur International Airport (KLIA), which officially opened in 1998. KLIA took over Subang's role as the country’s primary international gateway and Subang's operations were scaled back to regional and domestic flights.

### Skypark Terminal Transformation Plan

With Kuala Lumpur International Airport (KLIA) taking over as Malaysia’s primary international gateway in 1998, Subang Airport’s role significantly diminished. In response to this shift, the government initiated a redevelopment strategy, leading to the demolition of Terminal 1 in 2003.
Despite interest from AirAsia in establishing Subang as its operational base in 2004, the government maintained a policy limiting the airport’s use to general aviation and turboprop flights. This restriction ultimately set the stage for Subang Airport’s rebranding as Subang Skypark, redefining it as a hub focused on general and corporate aviation rather than mainstream commercial travel. This transformation allowed the facility to pivot towards serving private and regional aviation needs, positioning it as a key center for corporate aviation services in Malaysia.
In December 2007, Subang SkyPark Sdn Bhd announced a RM300 million transformation plan to revamp Terminal 3, enhancing its appeal as a corporate aviation hub. The project included the construction of a five-star executive lounge, expanded hangar facilities and improved infrastructure to support maintenance, repair and overhaul (MRO) services. The renovation added two large MRO hangars and ten parking hangars, making Subang an attractive base for private and corporate aviation.
The transformation included amenities for passengers and operators, such as additional office space, lecture rooms and a cafeteria within the new hangars. VistaJet, a global private jet service provider, chose Subang Skypark as its Malaysian base in August 2008, offering business jet services to destinations worldwide. In 2009, a RM40 million facelift was given to Subang Airport’s check-in terminals. While parking capacity remained a concern, valet services were introduced, with daily parking fees set at RM25. The airport saw further enhancements in accessibility when a rail link to Kuala Lumpur Sentral, operated by KTM Komuter, was added in 2018. This provided travelers a convenient transit option from central Kuala Lumpur.
On 28 October 2009, Prime Minister Datuk Seri Najib Tun Razak officiated the renovated Subang Skypark Terminal. He expressed confidence in Subang's potential to become a regional ASEAN hub, with a target of serving two million passengers annually.

### Asia Aerospace City

In August 2012, Subang SkyPark Sdn Bhd announced the SkyPark Nexus project, a RM420 million initiative aimed at transforming Subang SkyPark into a dynamic aerospace city. Spanning 4 to 4.8 hectares near Terminal 3, the proposed development included a boutique hotel, an aviation museum, a theme park and a retail mall with a total built-up area of one million square feet. A unique feature of the plan was a pedestrian bridge connecting the mall to the terminal, a concept rarely seen in urban airports. The project also included the construction of five state-of-the-art hangars for private and corporate jets, each accommodating up to five aircraft.
However, in 2015, the SkyPark Nexus project was put on hold due to various challenges, including changes in the development landscape and shifts in focus towards other initiatives. The project was later integrated into the broader Asia Aerospace City (AAC) development, a larger RM1.7 billion initiative led by Majlis Amanah Rakyat (Mara) and supported by Khazanah Nasional Bhd. The AAC project, which aims to position Subang as a major aerospace hub, is expected to encompass many of the elements originally proposed in the SkyPark Nexus project. Despite delays, the vision for transforming Subang SkyPark into a dynamic aerospace city continues through the AAC's revival, which focuses on enhancing aviation infrastructure and supporting aerospace-related industries.
In July 2021, Malaysia Airports Holdings Bhd (MAHB) announced the redevelopment of Terminal 2 into advanced hangars for business aviation under the LTSAAS Regeneration plan. The redevelopment, driven by demand from operators like Berjaya Air and Smooth Route, aims to increase the capacity of the Subang Aerotech Park by 280%. The project is expected to drive significant growth in Malaysia's business aviation sector, support the country's Aerospace Blueprint 2030 and solidify Subang's role as a competitive business aviation hub in the Asia-Pacific region. The transformation of Terminal 2 into hangars will be the first phase of this redevelopment.

### Subang Airport Regeneration Plan (SARP) and Resumption of Jet Services

The Subang Airport Regeneration Plan (SARP), approved in 2023, aims to transform Sultan Abdul Aziz Shah Airport into a major city airport and aviation hub by 2030. The plan is projected to generate a gross output of RM216.6 billion and a value-added contribution of RM93.7 billion over 25 years, accounting for approximately 1% of Selangor's GDP. It is also expected to create 8,000 direct jobs, with 11% in high-skilled, 48% in mid-skilled and 41% in low-skilled positions. As part of SARP's development, the airport's capacity is set to increase, reaching 5 million passengers annually in four to five years and 8 million passengers by 2030. The first phase of the plan involves a RM1.3 billion redevelopment to upgrade the airport into a city airport capable of handling 5 million passengers per year.
In line with the airport's transformation, Sultan Abdul Aziz Shah Airport resumed jet operations in July 2024 after a 22-year hiatus. Starting 1 August 2024, five airlines—AirAsia, Firefly, TransNusa, Batik Air Malaysia and Scoot—began operating flights from Subang to regional destinations. This move marked a shift from the airport's previous focus on turboprop, helicopter and private jet services, driven by the increasing demand at Kuala Lumpur International Airport (KLIA), which has reached full capacity.
To accommodate the resumption of jet services, the airport’s infrastructure was upgraded, including the reconfiguration of the apron to accommodate narrow-body aircraft like the Boeing 737 and Airbus A320. The terminal’s floor area was also expanded and new check-in counters and self-service kiosks were introduced to improve passenger experience. Subang’s passenger capacity is expected to double to 3 million annually with these upgrades.
As part of SARP, efforts are underway to reinstate the Skypark Link commuter train service, which connects Subang Airport to KL Sentral, further improving regional accessibility. Long-term plans for the airport also include establishing an aerospace ecosystem, developing business aviation facilities, and creating a drone testing site. These initiatives align with SARP’s vision of making Subang a comprehensive aviation and aerospace hub by 2030.
