The 13 flights a day on the HCMC-Hanoi route will still be maintained to meet the demand of many people trying to return to Hanoi from HCMC, they added.

One to two flights can be operated on routes from HCMC to localities like Da Nang, Quy Nhon, Cam Ranh and Buon Ma Thuot.

A representative of the Civil Aviation Authority of Vietnam (CAAV) said flights to southern provinces and cities will bestrictly supervised. Air carriers and airports will be facilitated in transporting people who want to return to their hometowns from HCMC and other southern localities.

All passengers on domestic flights will have to test negative for Covid-19. Major airports like Noi Bai in Hanoi and Tan Son Nhat in HCMC have the Covid-19 testing service.

Based on proposals from localities, the CAAV has stopped operating flights from HCMC to Thanh Hoa, Hai Phong and Quang Ninh. The Hanoi-HCMC route will be the only one connecting the north and the south.

Since the new wave began in late April, Vietnam has recorded 50,150 domestic Covid-19 cases. Nineteen southern provinces will impose social distancingcampaigns, starting Monday.
