Newark Liberty International Airport
Newark, New Jersey, (http://www.panynj.gov/Com...), John F. Kennedy International Airport (http://www.panynj.gov/avi...), and LaGuardia Airport (http://www.panynj.gov/Com...): The three major international airports in the New York City area offer service to just about anywhere. Westchester-based taxi and livery cars offer regular service to and from the three internationals from most areas of the county. New York City yellow cabs will take to you Westchester in a pinch, but the fares can be exorbitant. Instead, ask if your hotel offers shuttle service.
