AAA discount is likely to be less expensive than long-term parking and significantly more convenient (they even have the a/c running or the snow cleaned off when you arrive) as the buses/shuttles/trams/trains at jfk are *very* confusing, slow and crowded... and long-term parking can be sold out on popular travel weeks, whereas you can make a reservation in advance w/avistar!
