The four airlines operated a total of 22,896 flights during the month. The on-time performance index hit 89% with 20,366 flights, a slight drop of 0.5% from the same period of 2017.
Low-cost airline Vietjet Air had the highest number of delayed flights with 1,355, while the figure of the national flag carrier, Vietnam Airlines, was 804.
The budget carrier Jetstar Pacfic and Vasco reported 353 and 18 delayed flights in the month, respectively.
In the period, Vietnam Airlines recorded nine cancelled flights, or 0.1 percent 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 number of delayed and cancelled due to those errors.
