PETALING JAYA: The Kuala Lumpur International Airport (KLIA) has bagged the top spot in the global Airport Service Quality (ASQ) survey by Airports Council International (ACI). ASQ benchmarks the world’s best airports in terms of overall passenger satisfaction for terminal safety, facilities, services, and cleanliness. Malaysia Airports Holdings Berhad (MAHB) said KLIA achieved a perfect score of 5.0/5.0 for ASQ's category of over 40 million passengers per annum (mppa) in Q4 2020. "KLIA's improved global rank and service levels are also augmented by passing all elements in the Quality of Service (QoS) framework for Q3 2020 as recently announced by the Malaysian Aviation Commission (MAVCOM)," it said in a statement on Saturday (Jan 30).
