It is a 767-300 and there are no PTV's.
I was on the return flight (ATH-JFK) in 2003 and it was pretty standard. Drinks, meal, pre-landing snack... so I assume yours will be the same. I talked to one of the FA's for about 30 minutes and I seem to remember her mentioning its pretty senior on that scale.
The airport is WAY WAY outside the city (30 minutes+), so be prepared for a long ride into the center. The airport was very nice and quiet.
