Eleftherios Venizelos International Airport

Eleftherios Venizelos Airport (IATA: ATH, ICAO: LGAV) is the largest international airport in Greece, serving the city of Athens and region of Attica. It began operation on 28 March 2001 (in time for the 2004 Summer Olympics) and is the main base of Aegean Airlines, as well as other smaller Greek airlines. It replaced the old Ellinikon International Airport. It is currently a member of Group 1 of Airports Council International (over 25 million passengers) as of 2020, it is the 19th-busiest airport in Europe and the busiest and largest in the Balkans.

The airport currently has two terminals, the main terminal and the satellite terminal accessible by an underground link from the main terminal. It is designed to be extended in a modular approach over the ensuing years in order to accommodate increases in air travel. These extensions are planned in a six-phase framework. The first (and current) phase allowed the airport to accommodate 26 million passengers per year. When the airport originally opened, the current phase called for a capacity of only 16 million passengers per year; however, the capacity was able to increase without progressing to the next phase thanks to advanced IT logistics. The sixth and final expansion phase will allow the airport to accommodate an annual traffic of 50 million passengers, with the current layout leaving enough space for five more terminals to be added. As such, the parallel runway system currently in place has been designed to accommodate flight traffic with this high equivalent annual passenger load upon completion of the final expansion phase.
