Emirates is currently offering some great deals on flights to Greece. Until September 22 the airline is offering round-trip flight from New York that can be as cheap as $329. The interesting thing about this deal is that the more you but the more you save.
The airlines are offering extra discounts when multiple travelers book their flights together. But that also means that the tickets have to purchased at the same time and on the same itinerary, so all traveling from the same airports.
Even without the group discounts, the deals are still pretty great for both economy and business class. According to the airline, the travel dates are available to be used between September 26 and December 18, or December 25 to March 30, 2018.
