Flight
NYC has a tonne of airports, but JFK or Laguardia are going to be the most convenient... JFK has an air train that will take you to Jamaica Station. From here you can transfer towards Brooklyn and Manhattan, or catch the LIRR to Bay Shore and the Ferry Terminal.

Catching the LIRR from Penn Station to Long Island is easy. Choose Bay Shore or Babylon station as your destination. From Bay Shore, you can catch a shuttle bus, with David’s Shuttles, to the Ferry Terminal. It is $6 CASH per person one way.
