Keep in mind that this is a Shuttle oped flight on the E170. I would imagine this aircraft gets a jet way at least. I'm not exactly familiar with Delta's JFK operation with the exception of the remote area for most other Delta Connection flights.

This is besides the point. If I were flying this itinerary, I would pad the connection. Anything less than 2 hours is playing with fire in New York whether you're dealing with Delta Connection or not. Think about it, if you miss your transatlantic flight, then you got a BIG problem to deal with.
