KUALA LUMPUR — The Kuala Lumpur International Airport (KLIA) Aerotrain service faced another malfunction early this morning, forcing stranded passengers to walk along the tracks in the dark while carrying their luggage.

As of now, Malaysia Airports Holdings Berhad (MAHB) has yet to issue an official statement regarding the incident or provide updates on the current situation.

The Aerotrain system, which connects KLIA’s main terminal and satellite building, has come under increasing scrutiny in recent years due to its frequent technical failures and service disruptions.

One of the most notable breakdowns occurred on February 27, 2023, when an Aerotrain stalled midway on the track which led to a second train being dispatched to assist but also experienced technical difficulties, leaving passengers no choice but to walk to the satellite terminal.

Just days later, on March 1, 2023, another serious malfunction left 114 passengers stranded and they were forced to walk approximately 500 metres to the satellite building, and ten passengers reportedly missed their flights due to the delay.

Following a RM456 million upgrade project, the Aerotrain was relaunched on July 1, 2025, with promises of improved reliability. However, the system has since continued to face challenges. 

Between July 2 and September 30, the Aerotrain recorded 19 service disruptions, despite achieving a reported 99.19 per cent operational availability according to MAHB.

Today’s incident adds to growing public frustration over the reliability of KLIA’s internal transit system, raising further questions about maintenance standards and the effectiveness of recent upgrades.
