Delta recently changed my ATL-MAD direct flight to now connect through JFK (ATL-JFK-MAD). I would have 1hr35m in JFK. All Delta flights, no checked bags, all on one ticket. This is less than my usual comfort zone for a connection, especially since I'm connecting to an international flight. I've never been to JFK before but research indicates that I would arrive in terminal 4 and also depart for the international flight from terminal 4 - is this correct?
I'm trying to determine if it would be advisable to change to another flight or keep this itinerary.
