Hong Kong has banned Cathay Dragon from operating its Kuala Lumpur service until October 3, after the airline flew in five passengers from the Malaysian city who tested positive for Covid-19.

The passengers were travelling on flight KA734 from Kuala Lumpur to Hong Kong on September 18.

The airline says all of the passengers were connecting passengers travelling from India via an Air India Express flight, and they had provided a negative test result for Covid-19.

“We were… informed by the Civil Aviation Department (CAD) that Cathay Dragon’s passenger flights from Kuala Lumpur to Hong Kong will be prohibited from landing at Hong Kong International Airport for two weeks from 20 September to 3 October under Chapter 599H of the Laws of Hong Kong,” reads a media statement from Cathay Dragon.

The regional airline had been scheduled to operate three flights a week between Kuala Lumpur and Hong Kong.

“We are in the process of informing all affected passengers with the provision of refunds or other alternative flight arrangements,” said Cathay Dragon.

The airline says the aircraft operated on the flight from Kuala Lumpur has also been sent for deep cleaning.
