Note that on the way BACK, if you are also making a connex at JFK, The flight will come in to TERMINAL 4, and you will have to get to T5. You can take the airtrain but you may have to loop the whole airport first. (I don't think its walkable) See url below. You can also get info on the airtrain there.
