Emirates are back with a great deal between New York and Europe for 2 people. They are currently offering return fares from Newark to Athens for $353 each round trip. Dates are available into the new year. This is a great way to get to Europe as they offer excellent service in Economy aboard their 777.
Athens is a wonderful town to explore and of course there are numerous islands to visit in Greece. Fares are always much higher so if you have some annual leave to use before the end of the year, this could be the perfect deal to use them on.
