AirAsia may have earned flak for initially refusing to move to KLIA2 but the reason for its reluctance has become apparent a year on, with the airport still plagued with problems.

AirAsia group chief executive officer Tony Fernandes lamented about this in a Twitter posting today.

"After more than one year, remedial work still being done.

If only someone listened to us. So much wasted money," he said in his posting.

Fernandes (photo) did not specifically mention KLIA2 but posted a photograph of what appeared to be remedial work being conducted on the taxiway of KLIA2.

AirAsia initially refused to move to KLIA2, citing "pressing issues", such as defects on the taxiway and runway, in a statement on April 1, 2014.

"We believe it is crucial to ensure that whole, remedial steps are undertaken prior to a transfer, which will mitigate risks relating to any potential aviation incidents," the company said then.

Four days later, the company earned a rebuke from Prime Minister Najib Abdul Razak, who ordered AirAsia to move to the new airport.

The company finally agreed to move to KLIA2 on May 9, 2014, after the government said it would rope in  Civil Aviation Organisation (ICAO) to evaluate the long-term safety of KLIA2.
