The only airport in Gambia is at Yundum. After World War II, Yundum airport was used for passenger flights. Both British South American Airways and the British Overseas Airways Corporation had services, the former moving its service to Dakar, which had a concrete runway (as opposed to pierced steel planking). The airport was rebuilt in 1963 and the building is still in use today.
Zambia Airways launched service from Lusaka to New York via Banjul in December 1990 It flew the route with a McDonnell Douglas DC-10. Nevertheless, financial difficulties forced the carrier to suspend it just three months later. In February 2001, Ghana Airways commenced a flight from Banjul to Baltimore, which originated in Accra. Cooperation among Ghana Airways, Gambia International Airlines, and the Ghanaian and Gambian governments had given rise to the service. In June 2006, North American Airlines inaugurated a link to Baltimore using Boeing 767s, but it only lasted seven months.
The head office of the Gambia Civil Aviation Authority is located on the airport property.
In the event of an emergency on any of the NASA Space Shuttles, Banjul International Airport had been selected as an augmented landing site. Gambia was the perfect location when the shuttle was launched with a low, 28-degree inclination. In 2001 NASA announced that Banjul airport would no longer be used as an augmented landing site because future shuttle launches would take place at inclinations of up at 51.6 degrees to reach the International Space Station, making air bases in Spain and France more suitable for an emergency landing.
The airport was the main hub of Gambia Bird until the airline ceased operations in late 2014.
