A nonstop flight from Boston to Athens takes about 9 hours 10 minutes, the fastest time Google Flights listed for the route on October 1, 2026, and Delta is the airline that flies it nonstop from Logan Airport. Coming home takes longer, about 10 hours 36 minutes nonstop, because of the westbound headwinds. If you are going to a Greek island or to Thessaloniki, plan on 11 to 12 hours or more with a connection.
Athens is about 4,740 miles from Boston in a straight line, and every other Greek airport needs at least one stop from Logan. Below are the times by destination, who flies the route, and what to know before you book.

Can you fly direct from Boston to Greece?
Yes, to Athens only. Google Flights listed Delta with seven nonstop flights a week from Boston to Athens, one a day, when checked on October 1, 2026. Airline schedules change by season, so check your exact dates before planning around the nonstop, especially for winter travel. You can compare Boston to Athens fares on Expedia.
For any other Greek airport, you connect. That can mean a connection in Athens onto a domestic flight or a ferry, or a stop at a European hub. Google Flights listed connecting itineraries from Boston to Athens on carriers including Lufthansa, British Airways, Air Canada, United and TAP Air Portugal.
Why is the flight home longer?
Eastbound flights across the Atlantic usually ride the prevailing westerly winds, and westbound flights fly into them. That is why the fastest nonstop listed from Athens to Boston, 10 hours 36 minutes, is more than an hour longer than the outbound flight.
Boston to Athens or a European stopover?
The nonstop is the quickest way, and the obvious choice for a short trip. A one-stop routing is worth considering when the nonstop is sold out or expensive, or when you are heading straight to an island and would connect anyway. If you would like to break the trip in Europe, our guide to Boston to Lisbon flights covers one gateway with nonstop service from Logan.
Before you fly from Logan
US citizens need a valid passport for Greece; check the State Department's travel site for the current entry rules and passport-validity requirements before you book.
