Hourly service between Boston's Logan Airport (BOS), New York's Laguarida Airport (LGA), and Washington Reagan National (DCA) and Dulles (IAD) Airports. They fly single-class Boeing 737, MD-80, and new Airbus A320 aircraft. Very convenient for road warriors. They also give you free magazines and newspapers, and orange juice and coffee in the terminal. Oh, and free alcohol on the airplane.
