Tunis–Carthage Airport (French: Aéroport de Tunis-Carthage, Arabic: مطار تونس قرطاج الدولي, IATA: TUN, ICAO: DTTA) is the international airport of Tunis, the capital of Tunisia. It serves as the home base for Tunisair, Tunisair Express, Nouvelair Tunisia, and Tunisavia. The airport is named for the historic city of Carthage, located just east of the airport. The history of the airport dates back to 1920 when the first seaplane base in Tunisia was built on the Lake of Tunis for the seaplanes of Compagnie Aéronavale.The Tunis Airfield opened in 1938, serving around 5,800 passengers annually on the Paris-Tunis route.
During World War II, the airport was used by the United States Air Force Twelfth Air Force as a headquarters and command control base for the Italian Campaign of 1943. Once the combat units moved to Italy, Air Transport Command used the airport as a major transshipment hub for cargo, transiting aircraft and personnel. It functioned as a stopover en route to Algiers airport or to Mellaha Field near Tripoli on the North African Cairo-Dakar transport route. Later, as the Allied forces advanced, it also flew personnel and cargo to Naples, Italy.
Construction on the Tunis-Carthage Airport, which was fully funded by France, began in 1944, and in 1948 the airport become the main hub for Tunisair. The airline started operations with Douglas DC-3s flying from Tunis-Carthage Airport to Marseille, Ajaccio, Bastia, Algiers, Rome, Sfax, Djerba, and Tripoli. The passenger traffic grew steadily from 1951 when 56,400 passengers were carried, 33,400 of them by Air France. The airport offered a convenient stop-over point for several other French airlines over the years, including Aigle Azur with a stop in Tunis on the Paris-Brazzaville route, and TAI (Intercontinental Air Transport) with a stop in Tunis on its Paris-Saigon route. Among foreign companies, the TWA is present, whose lines Rome-New York and Rome-Bombay make stop in Tunis, and the LAI (Italian company) which makes the connection Rome-Palermo-Tunis.
In 1997 the airport terminal was expanded to 57,448 m2 ; it consists of two floors (departure and arrival) and has a capacity of 4,400,000 passengers per year. In 2005 the terminal was expanded another 5,500 m2, and now has a capacity of 500,000 more passengers annually. On 23 September 2006 a new terminal opened for charter flights.
