Flying in to KLIA after midnight? Buses replace Aerotrain from 12am to 5am during software works

On October 7, the KLIA Aerotrain is set to halt operations between midnight and 5am as part of software maintenance in October and November. Buses will replace the train during these hours, transferring passengers between the Main Terminal and Satellite Building. The first phase, field testing, will take place from October 8 to 17, with the update being installed and tested under real-world conditions. Following positive safety assessments, the update will be permanently implemented from November 28 to December 1.

KLIA has assured that a comprehensive bus service will operate throughout these works, as part of its contingency plans. Passengers should consult signage leading to the bus lounge, where transfer buses will be available, or seek assistance from ground staff.

KLIA's Chief Operating Officer, Adam Nicholas Wilson, emphasized the company's commitment to maintaining a dependable and seamless service for passengers. The Aerotrain has operated for 20,000 continuous hours, achieving a remarkable 99.9% availability since June. Over the past 1.5 years, it has completed 167,481 return trips and transported approximately 23.55 million passengers.
