The blue line links to Eleftherios Venizelos International Airport, but a special 8-euro ticket is required. The metro runs between 5am and 12am from Sunday to Thursday and from 5am to 2am on Fridays and Saturdays.
By bus/trolley: Athens feature a comprehensive bus and trolley-bus network. Time schedules usually depend on the route, however most buses run between 5.30am and 12am. A few 24-hour routes are available, including X95 between Syntagma Square and the airport.
By tram: The tram was introduced to Athenians in 2004 and was fashioned in order to link the city center with the Olympic facilities in southeastern suburbs, which were not served by metro; it is still the most comfortable way to get to the southeastern suburbs, given that you are not in a hurry.
By taxi: Taxis are still quite inexpensive compared to other European capitals. A fixed price is set for rides from the airport to the city center: a 35-euro tariff on day shift (from 5am to 12am) and a 50-euro tariff on night shift.
