Athens International Airport, 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. Athens International is the 28th busiest airport in Europe.

PS: I would have expected a nice restaurant after check-in. You can only have a sandwich, a beer or a burger.
