I've ascertained that my daughter-in-law's flight from SA will be arriving at Terminal 4 at JFK, and my domestic flight from Chicago at Terminal 3. I have also Google'd JFK and got a wonderful printout of all the Terminals, and some info on a Skytrain. Would appreciate advice here pse. It seems it might be possible to get on the Skytrain and travel from Terminal 3 to Terminal 4? If so, I really need to know what meeting point we could arrange for Terminal 4 pse. Would prefer that she stayed at Terminal 4, bearing in mind she's never been to JFK, and I'd rather try to find her, than vice versa. (Not that it is not going to be one heck of a mission for me!).
