About 50 passengers, mostly Chinese tourists and businessmen, attended the launch ceremony at the Pyongyang Sunan International Airport.

Air Koryo, a DPRK airline, will operate the twice weekly flights, taking off from Pyongyang at 9:00am local time and returning to the DRPK capital city at 11:40am.

Air Koryo has regular flights to Beijing and Shenyang, which is also in Northeast China. The charter flight to Dandong is its third route to China.

Facing Sinuiju of DPRK across the Yalu River, Dandong in Liaoning province of Northeast China has become a transport hub connecting the two countries.
