By far the easiest way to get to Greece is by air. There are direct or corresponding flights to many Greek destinations from diverse major airports. Even if your starting point is North America, Australia, New Zealand or South Africa, the most cost-effective way to Greece may well be to get to London – or Amsterdam, Frankfurt or another Northern European hub – and pick up an onward flight from there.
Depending on your country of origin you will have to book your ticket and plan your travel to Greece. Airfares are higher during summer time, mainly July and August. May, June and September are also popular, and since far fewer flights operate through the winter, bargains are rare at any time. Booking your airtickets early, can reduce your travel costs. There are great fares to Greece during the off-season period.
The most common destination cities to enter Greece by air are: Athens (the capital) and Thessaloniki.
The airport is accessible via Metro Line 3 “Aghia Marina – Athens International Airport”.
The ticket costs 10.00 Euros and it is valid for one trip to or from the airport and you can go directly to the city center, like Suntagma Square, Monastiraki, etc.
