The Vietnam Airlines Group reported a loss of over VND2.6 trillion ($110 million) in the first quarter as the Covid-19 pandemic severely impacted the aviation industry.
On Thursday, Vietnam lifted restrictions on the number of flights between Hanoi, HCMC and Da Nang City. Passengers are no longer required to sit one seat away from each other, but still need to wear face masks and keep a distance of one meter from each other during flight procedures.
The number of flights by local carriers dropped by up to 85 percent year-on-year in the March 18 – April 19 period, according to the CAAV.
Last year, domestic airlines served 55.3 million passengers, up 11 percent year-on-year, General Statistics Office data shows.
