China Southern Airlines has cancelled plans to launch a twice weekly Guangzhou-Kota Kinabalu service.
The carrier was due to begin the service on 23 January. Its spokeswoman did not give a reason for the change.
China Southern will also increase the frequency of its Guangzhou-Vancouver route, from thrice weekly to daily, on 17 June, adds the spokeswoman.
Innovata schedules show that China Southern is the only operator on the Guangzhou-Vancouver route.
