Pyongyang Sunan International Airport — Pyongyang, North Korea

Pyongyang Sunan International Airport, using the code FNJ, functions as the almost exclusive air link between North Korea and the outside world, making it one of the most restricted airports on earth. Flag carrier Air Koryo operates most services from the field, supplemented by a limited number of Air China flights connecting to Beijing. A newer terminal building, completed around the middle of the previous decade, replaced older Soviet-era structures and introduced a more modern design intended partly to project an image of national progress. Commercial passenger volume remains extremely small by global standards, constrained by sanctions, travel restrictions, and the tightly managed nature of North Korean tourism. Air Koryo's aging fleet has for years appeared on lists of carriers restricted from European airspace. Foreign visitors passing through FNJ typically travel as part of tightly guided tour groups rather than independently.
