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. Independent research has shown the seven-abreast seating concept in economy is popular because it places 87 percent of the seats next to a window or aisle.
