• Airports MacAthur airport in Islip, Long Island is by far the most convenient airport to Stony Brook. It is served by USAir, Delta, American and Northwest (last I checked), is sixteen miles from the campus and takes about 30 minutes to drive between campus and airport. Laguardia and Kennedy are about 50 miles away, but I would leave about three hours for ground transport, to be on the safe side. Newark airport off Long Island and the ground transport vans don't usually go there directly. You would have to take some ground transport to Manhattan and then take the train from Penn Station to Stony Brook. You should probably leave 4 or 5 hours for ground transport to Stony Brook. I have never flown in or out of Newark, so I don't know exactly how this works. The other three airports are definitely preferable.
• Airport Ground Transport. From Islip, Kennedy or Laguardia I usually use the shared van service offered by Classic Airport Shareride. Their number is 631-567-5100. Advanced reservations are a good idea. The fare from Laguardia or Kennedy to Stony Brook is around $40 (ask if there is a special rate for going to the Stony Brook campus; there used to be). From Islip, I am not sure, but it should be less (maybe around $20). One can also take a bus (Gray line) from Kennedy or LaGuardia to Manhattan (I think there is a stop at Penn Station) and then take the Long Island railroad out to Stony Brook. There is a also a water taxi from the Delta shuttle terminal at Laguardia which will take you to 34th street at the east river and then it is a few blocks to Penn station (which is also on 34th street). I think the water taxi is $15, but have never taken it myself.
