Call me biased, but the new Athens International, Eleftherios Venizelos is great........and don't just take my word for it.
In the latest IATA survey of Passengers (Remember them.?? ---- SLF, aka the Punters who pay all our wages) voted Athens the best Airport Globally, yes globally, in the 10-15 Millionpax per annum bracket. Not bad when you think what the old Hellenikon toilet was like.
From the heaven of the Greek Islands, to the hell of the Greek Airports.!! All changed now.
Oh, by the way, it's staffed with some gorgeous black eyed beauties...... sigh.!
