After a departure flight with a 1h30min delay due to a late plane, this return flight had a number of complications:
Check-in took 1 hour and 30 minutes (5 windows for two plane with 360 passengers at JFK) and as a result the plane took off with a 1h30min delay and arrived in Paris 30 minutes late.
What's more, only breakfast was served on board, and the slow check-in time meant that the passengers didn't have time to eat something at the airport.
Despite the delay and the 1h30min wait on the plane, we weren't provided sandwiches or anything to tide us over.
Also, I am 6'1" and I don't recommend this plane for people of my size.
Finally, the plane didn't provide tablets, just communal screens.
Even though the flight attendants were very nice, this round trip was not worth the 950 euros it cost.
