The airline’s group chief executive officer Tony Fernandes said on Twitter that the airport regulator and operator should support the stakeholders – both the airlines and passengers – with fair treatment.

“All we have ever asked is for Malaysia Airports to understand our model and help us. Help us create more jobs. We are a low-cost carrier, its largest customer.

“For 18 years all we have asked is to have an airport that’s a partner. Like we have with GE Aviation, Airbus or Credit Suisse Group AG,” he said.

Fernandes again wondered why the passenger service charge (PSC) at the Langkawi International Airport and Kuala Lumpur International Airport 2 (klia2) was the same as that for the Kuala Lumpur International Airport (KLIA).

He believed the rate is ‘unfair’ as these airports have different facilities and service offerings, plus the poor gate condition at klia2 should be taken into consideration, rather than imposing the same airport tax.

“Mavcom is supposed to look after passenger interest. Are they?” he asked.

“Charge unfair airport tax to our guests. No regulation on the airport? Worse, every passenger (needs to) pay RM1 every time they fly so Mavcom can have a budget!” he added.
