Bus number 68 will start at Melinh Plaza Ha Dong on Ha Cau Street and stop en route at the Ha Dong Post Office, the Vietnam Museum of Ethnology and Nghia Do Park.
The 60-seat bus will have wifi on board.
The fare is VND40,000 ($1.71) for one way. There will be a bus every 30 minutes from 5 a.m. to 11 p.m. A trip will take around 70 minutes.
The service is expected to draw away passengers going to the airport by personal vehicles and taxis, thus helping reducing traffic, the city Department of Transport said.
