Ndjili International Airport — Kinshasa, Democratic Republic of the Congo

Ndjili International Airport, coded FIH, serves Kinshasa, the sprawling capital of the Democratic Republic of Congo and one of Africa's largest cities by population, sitting along the banks of the mighty Congo River across from Brazzaville in the neighboring Republic of Congo. The airport takes its name from the surrounding Ndjili district and river tributary. As the country's primary international gateway, FIH handles a mix of long-haul connections to Europe, regional West and Central African routes, and considerable humanitarian and mining-related cargo traffic given Congo's vast mineral wealth. Kinshasa and Brazzaville rank among the closest pair of national capitals in the world, separated only by the river itself, a geographic quirk visible to arriving passengers. Infrastructure challenges have periodically affected operations, though FIH remains central to Congo's connection with the wider world.
