AirAsia has filed a legal challenge in an attempt to force Malaysian regulators to rule on long-running disputes between the airline and Kuala Lumpur airport operator Malaysia Airports.

The dispute relates to the passenger service charge (PSC), and airline accusations of poor service levels at Kuala Lumpur International Airport’s Terminal 2 (KLIA2).

AirAsia and the airport have filed charges against each other on these issues, with the airline refusing to collect the increased PSC, which they say is unfair. AirAsia X is supporting its sister carrier.

The carriers have also filed a claim of RM480 million ($115 million) in damages they say were caused by inadequate level of service at KLIA2. The airlines assert they have tried to resolve these issues through the Malaysian Aviation Commission’s (MAVCOM) statutory dispute structure, but MAVCOM has “refused to decide on the disputes.”  

AirAsia contends that MAVCOM has a “statutory duty” under Malaysian law to decide on these matters once mediation between the two parties has failed. So the two airlines are asking for a court order to “compel MAVCOM to adjudicate” on the dispute with the airport.
