Delta moves to smaller planes for N.Y.-D.C. shuttle: Embraer jets carrying 76 passengers will soon replace the 142-passenger MD-88s operated by Delta Shuttle on its New York-Washington route. The company plans to convert 50% of its flights to the smaller E-175 aircraft by Jan. 5, and 100% by the end of March. Delta said the smaller aircraft will better match reduced demand on the route.
