More than 10,000 flights were delayed or cancelled in the first quarter of this year, according to the Civil Aviation Authority of Vietnam (CAAV).

These flights accounted for 13.5 per cent of the total 74,165 flights operated by four domestic carriers – Vietnam Airlines, Vietjet, Jetstar Pacific and Vietnam Air Services Company (Vasco) in the reviewed period.

Vasco, a low-cost airline of national carrier Vietnam Airlines, was the best performer in terms of punctuality, with 3,336 on-time flights or 97.7 per cent of the total 3,415 flights.

Vietnam Airlines came second, with 29,321 on-time flights, or 90.2 per cent of the total 32,504 flights.

Vietjet and Jetstar Pacific operated 29,261 and 8,985 flights, with their rates of delayed and cancelled flights being 16.6 per cent and 21.1 per cent, respectively.

CAAV blamed flight unpunctuality to subjective reasons from airlines as well as weather conditions, flight management and late arrival of airplanes.

According to CAAV, Vietjet recorded the highest increase in flights by 26.6 per cent, followed by Vasco (23.2 per cent), Jetstar Pacific (10.9 per cent) and Vietnam Airlines (3.9 per cent). — VNS
