The Boeing 767 family is a complete family of airplanes providing maximum market versatility in the 200- to 300-seat market. The Boeing 767 family includes three passenger models -- the 767-200ER, 767-300ER and 767-400ER -- and a freighter, which is based on the 767-300ER fuselage. The twin-engine 767 -- sized between the single-aisle 757 and the larger, twin-aisle 777 -- has built a reputation among airlines for its profitability and comfort. The 767 flies across the Atlantic more frequently than all other jetliners combined, and uses about 60 gallons (227 l) of fuel per passenger to get from New York to London on board a 767-400ER. The same volume of gasoline would propel an economy car about half of that distance.
