I'm looking at the Terminal 7 map and don't see the connection to the AirTrain. I watched a video on you tube and it looks like you have to exit the terminal, pass where the taxis are, then there is an escalator to the AirTrain. Is that correct? Do you have to re-clear security when you leave Terminal 7 and go to another terminal (I am going to Terminal 4 for an international flight).
