If you are traveling to the town of Newberg, that is one of the most popular towns in this area that is just to the west of the airport, you can take the buses operated by Leprechaun Lines that can make the trip from the airport to the center of the town in about 20min. These buses arrive at the corner of Broadway and Grand Street in the center of Newberg. Since public transportation can be somewhat limited in this area, a better choice might be to rent a car from one of the four major rental car companies that operate at the New York Stewart International Airport.
