PETALING JAYA: There have been more delayed flights out of Kuala Lumpur's international airports to China this year compared to last year, said the Department of Civil Aviation (DCA).
DCA director-general Datuk Azharuddin Abdul Rahman (pic) said the department was particularly concerned with delays for China-bound flights.
"The percentage of delayed flights on departure at KLIA/KLIA2 varies from 9% to 37%, an increase of 2% to 23% when compared to the same months in 2016," he said in a statement on Friday.
The data was based on delays for morning, afternoon and evening departures from January to May for this year and last year.
Azharuddin explained that flight delays were commonly the result of airspace and airport congestion, especially within China, as well as airspace constraints imposed on civil or commercial flights in the destination country or countries along the route.
Furthermore, large-scale weather deviations can impact airspace capacity and thus cause delays.
"It should be noted that all departing flights from any departure point are subject to the readiness of the destination country or countries along the route to receive such flights," said Azharuddin.
He said that Malaysia, along with other countries in the region, would work together with the International Civil Aviation Organisation to minimise airspace and airport constraints in order to reduce flight departure delays and lessen the impact of delays on the public.
