Minister of Transportation Dinh La Thang asked the Civil Aviation Authority of Vietnam (CAAV) on Friday to establish punishments for air carriers for delays or cancellations of flights.
Thang strongly criticized CAAV for a huge rise in flight delays and cancellations in the first half of this year.
According to CAAV statistics, between January and June, more than 20 percent of the total 74,000 domestic flights were delayed, an increase of 5.2 percentage point year-on-year.
During the same period, 3.2 percent of the flights were canceled, an increase of 0.5 percentage point annually.
VietJet Air had the highest rate of delayed flights with 40.4 percent; VASCO reported the lowest rate with 10.2 percent.
The CAAV blamed the delays on technical problems, weather, staff and passenger problems, a lack of accommodation at airports, congested air traffic and commercial factors.

Minister Thang asked the CAAV to create a punishment matrix for air carriers in the event of flight delays and cancellations that includes revoking an air carrier's operating license, he said.
He also asked air carriers to review the role of its staff plays in causing the delays and cancellations.
Vo Huy Cuong, deputy chief of CAAV, said Wednesday that the agency will order air carriers to prepare more back-up aircraft to prevent flight delays or cancellations.
