I am trying to catch an AF internaltional flight in Terminal 1 after arriving on a Delta codeshare flight in Terminal 3. I have a close connection and am hoping I dont have to leave a secured area to get to Terminal 1 to catch an Air France flight. I only have about 1.5 hours connection time. Is this possible or will I have to go out and catch the AirTrain?

And, if I do have to leave a secure area and go back through security at Term 1, what are my chances of running into time trouble? My flight is this Tuesday night leaving JFK at 10:55 pm for Paris.

Thanks for any assistance!
