Inside Kuala Lumpur International Airport (KLIA): Southeast Asia’s Global Aviation Powerhouse

KLIA
Kuala Lumpur International Airport—commonly known as KLIA—is Malaysia’s main international gateway and one of the largest transportation hubs in both Southeast Asia and the world. Located in Sepang, about 45 kilometers south of Kuala Lumpur city center, the airport is a key connector for global travelers.
In 2018, KLIA handled nearly 60 million passengers, making it the 23rd busiest airport in the world by passenger volume.
Spanning 100 square kilometers, the airport was built on what was once agricultural land. Today, it features three runways and two main terminals, with Terminal 1 also including a satellite building to accommodate international flights.

History of Kuala Lumpur International Airport (KLIA)

The story of Kuala Lumpur International Airport (KLIA) began on June 1, 1993, with the groundbreaking ceremony for what would become one of Southeast Asia’s largest and most advanced aviation hubs. The need for a new airport arose because the existing Sultan Abdul Aziz Shah Airport (also known as SkyPark Subang) could no longer support the growing volume of air traffic.

The new airport was designed by renowned Japanese architect Kisho Kurokawa, known for blending modern design with natural elements.
Following the completion of KLIA:
  • The first terminal at Subang Airport was demolished.
  • The third terminal was repurposed for charter flights.
  • The IATA airport code KUL was transferred to KLIA, while SZB was assigned to the former Subang Airport.
KLIA officially opened on June 27, 1998, and features three runways, capable of handling up to 78 aircraft landings per hour.
One of the unique highlights of KLIA1’s satellite terminal is the Jungle Boardwalk—a lush indoor leisure area that brings a touch of Malaysia’s tropical rainforest into the airport environment.

The Main Terminal – KLIA1

Main terminal KLIA1.
KLIA1 is the airport’s primary terminal and is located between two runways, covering a total area of 390,000 square meters. It features 216 check-in counters, and since 2007, has also offered self-service check-in kiosks, introduced by KLM—one of the first airlines to implement this technology at the airport.
Gate Layout:
  • Domestic flights use Gates A and B
  • International flights use Gates G and H
  • Gate C is located in the satellite terminal, which is connected to the main terminal via the Aerotrain
The Aerotrain journey takes just 2 minutes, with trains running every 5 minutes. However, this short trip can become slightly inconvenient if your departure gate is changed between the satellite terminal and the main terminal. In such cases, you’ll need to travel between terminals again, so it’s important to monitor flight information displays carefully while at the airport.
Satellite terminal KLIA1
Satellite Terminal Highlights:
  • Covers approximately 176,000 square meters
  • Exclusively serves international flights
  • Offers a wide range of Duty-Free shops, boutiques (such as Burberry, Harrods, Montblanc, and Salvatore Ferragamo), and restaurants
So if you didn’t spend all your ringgit in the main terminal, you’ll have plenty of opportunities here.
Amenities at KLIA:
  • Free internet access
  • Multiple lounges, including those with children’s playrooms and small movie theaters
