To add some info for your trip. Delta's operations at JFK are in 2 connected terminals (T2 & T3). There are moving walkways between the two terminals airside. However, if you connect in from a non-Delta flight (i.e. AA) you would need to use the AirTrain and re-clear security. Also, Delta adds additional time into their flight times to & from JFK. According to flightaware.com, the time from wheels up to wheels down is roughly 1 hour. This would mean there is roughly 45 minutes added to the schedule for any issues (late arriving plane, taxi time, waiting for a gate, etc.). However, this won't guarantee that you arrive in JFK early. Here are the flight stats for CLE -> JFK. http://www.flightstats.com/go/FlightRating...ivalAirport=JFK
