Sized between the single-aisle 737 Next Generation and the twin-aisle 777, the versatile 767 earned a reputation among airlines for its profitability and comfort. The Boeing 767's cabin is more than 4 feet (1.2 m) wider than single-aisle jetliners, and the 767's versatile design allows customers to select four, five, six, seven or eight abreast seating to best suit their operational requirements.
