Athens International Airport Eleftherios Venizelos (Greek: Διεθνής Αερολιμένας Αθηνών «Ελευθέριος Βενιζέλος», Diethnís Aeroliménas Athinón "Elefthérios Venizélos") (IATA: ATH, ICAO: LGAV), commonly initialized as "AIA", began operation on 28 March 2001 and is the primary international airport that serves the city of Athens and the region of Attica. It is Greece's busiest airport and it serves as the hub and main base of Aegean Airlines as well as other Greek airlines. The airport is the 27th-busiest airport in Europe.
The airport was constructed to replace the now-closed Athens (Ellinikon) International Airport, as the latter had reached its saturation point with no physical space for further growth. Studies for a new airport had been carried out from as early as the 1970s, with as many as 19 different locations being looked at before an area close to the town of Spata was chosen as suitable.
The airport is named after Elefthérios Venizélos, the prominent Cretan political figure and Prime Minister of Greece, who made a significant contribution to the development of Greek aviation and the Hellenic Air Force in the 1930s.
