Aegean Airlines is offering 20% off some of its flights to Greece from locations in Europe and the Middle East, including Budapest, Tel Aviv, and Prague. For travelers from the United States, the direct flight via Vienna might be the most convenient connection. Some flights being offered don't go through Athens but through Thessaloniki or Kalamata, offering the possibility of skipping a connection through Athens entirely.
Flights have to be booked between now and March 4th (Greek Time) and are good on flights between April 1st and June 30th, 2013.
They are also offering a similar discount on flights between Larnaca, Cyprus and Athens, London, and Kiev.
