The Boeing 747, which is also known as the jumbo jet , is the second largest passenger airliner after the Airbus A380. Until the first commercial flight of the A380 in 2006, however, it no longer remains the largest passenger aircraft in commercial service.
The four-engine 747, produced by Boeing Commercial Airplanes, uses a two-deck configuration, the small upper deck is usually used for business-class passengers. A typical three-class layout accommodates about 400 passengers while a one-class layout accommodates a maximum of 600 passengers. The hump created by the upper deck has made the 747 a highly recognisable icon of air travel.
