Air Koryo
Samjiyŏn is served by the Korean People's Air Force along with the national flag carrier Air Koryo which operates scheduled flights and charter services between Samjiyŏn and P'yŏngyang, Wŏnsan and Ch'ŏngjin. In 2005, the airport was closed due to major renovations, which were partially underwritten by the Hyundai corporation.
