Boeing 767 is an American wide-body aircraft and features a 21.1-foot fuselage extension over the 767-200, achieved by additional sections inserted before and after the wings for an overall length of 180.25 ft (54.9 m). Following is Delta's Boeing 767-300 V4 Seating Chart showing First Class, Comfort Class, and Economy Class. This Seating Chart provided by Delta Airlines helps a passenger understand their airlines' important areas, like Lavatory, Wardrobe, Exit, Cradle, Power Socket, and more. As you can see from the Seating Chart here, an optional mid-cabin exit door is positioned ahead of the wings on the left, while more powerful Pratty & Whitney and Rolls-Royce RB211 engines became prominent.
