[B]JFK has been the worst in my experience... especially when flying out of Terminal 9 and due to all the construction. Traffic around the airport is horrible, and therefore, the shuttles are infrequent. The shuttle busses have to stop at nearly each terminal... so from the time you drop off your car until you get to Terminal 9 can be up to 45 minutes if the airport is busy. However, as construction finishes, this will improve.
I tend to agree that JFK terminal 8-9 is terrible. Hopefully if Airtrain ever gets going this will improve. The station at Fedreal circle is right near all the rental car counters.
