Steve, no FedEx or Lufthansas at JFK? They are daily multiple times... so you will easily get to see one or more :-)
Then once in a while you get Cargoitalia, Finnair (I am still waiting for a good catch) and really rare, Saudi Cargo. There are others like EVA MD-11 which is rare as well as I believe one or two KLMs left that make it here...
at EWR you can get a hundred FedExes in one day LOL
