Travel demand by air surges when summer is nearing
Up to 90 percent of flights from Hanoi to Dong Hoi and Phu Cat airports have been sold.
Large numbers of flight bookings have been made on flights from HCM City to Tuy Hoa, Phu Quoc and Cam Ranh.
Ticket prices have been on a sharp rise due to higher demand. CAAV has asked domestic airlines to consider increasing the flight frequency from Hanoi/HCM City to Phu Quoc, Phu Yen, Binh Dinh, Nha Trang and Con Dao.
Vietnamese airlines will provide an additional number of 5,000 tickets per day to meet the demand on the coming Reunification Day on April 30, and International Labour Day on May 1.
The Ministry of Transport has urged airlines to take measures to mitigate flight cancellations and delays.
