During the month Vietnam Airlines recorded nine cancelled flights, or 0.1 per cent of its total flights, while Vietjet Air and Vasco each cancelled six flights. Notably, Jetstar Pacific saw no flight cancellation in October.

According to the Civil Aviation Authority of Vietnam (CAAV), the late return of planes was the main cause of the delays and cancellations.

Other reasons include airports’ limited infrastructure and services, flight management and operation, weather and technical issues, the agency said.

The CAAV has asked relevant agencies and airlines to review and arrange personnel to repair technical errors, reducing the number of delayed and cancelled flights due to those errors. — VNS
