Delta Air Lines will next summer fly up to 11 weekly flights between New York JFK and Athens.
The US carrier will start operating a five-times weekly service to the Greek capital on March 30, increasing to a daily service on May 2.
Then, on June 2, it will add four more weekly flights onto the route, bringing the total to 11.
Delta will roster A330-300 and B767-300 aircraft, featuring fully-flat seats with direct aisle access in a 1-2-1 configuration in Business Elite, onto the route.
When running 11 weekly services the schedule will see daily flight DL263 depart Athens at 1200 and land at JFK at 1545, with return flight DL042 taking-off from JFK at 1630 and arriving in Athens at 0930 the next day.
Flight DL216 will operate on Mondays, Wednesdays, Thursdays and Saturdays, departing Athens 1430 and landing in New York at 1825. Flight DL417 will leave New York on Tuesdays, Wednesdays, Fridays and Sundays, leaving JFK at 1930 and arriving in Athens at 1245 the next day.
Perry Cantarutti, Delta's senior vice president for Europe, Middle East and Africa, said: "We hope that by increasing our frequency next year, we are able to facilitate even higher tourism and business traffic as Greece continues its economic recovery."
All services from Athens are operated in conjunction with Delta's joint venture partners Air France-KLM and Alitalia.
Delta last week announced it is expanding its luxury car terminal transfer service to New York La Guardia, Seattle Tacoma and Detroit Metropolitan airports this month (see news, November 7).
