Laajarunkokoneet, often translated as wide-body aircraft or jumbo jets, are large passenger airplanes characterized by their wide fuselage. This design allows for two aisles in the passenger cabin, differentiating them from narrow-body aircraft which typically have a single aisle. The increased width also enables a greater passenger capacity and cargo volume.

The first wide-body aircraft, the Boeing 747, entered service in 1970. Its success paved the way for other manufacturers to develop their own wide-body models, including the McDonnell Douglas DC-10 and the Lockheed L-1011 TriStar. Modern wide-body aircraft are typically twin-engine or four-engine jets designed for long-haul flights, connecting major cities across continents.

Key manufacturers of wide-body aircraft include Boeing and Airbus. Boeing's current wide-body offerings include the 777, 787 Dreamliner, and the 747-8. Airbus produces the A330, A340, A350 XWB, and the superjumbo A380. These aircraft are crucial for international travel, offering greater efficiency and comfort for long-distance journeys. Their larger size also contributes to economies of scale, potentially lowering per-passenger operating costs.
