The Boeing 737 is a narrow-body airliner produced by Boeing since 1967. Originally developed as a short-range, lower-cost twin-engine airliner derived from Boeing's 707 and 727, the 737 has developed into a family of ten passenger models with capacities ranging from 85 to 215 passengers, making it the best-selling jet airliner in the history of aviation.
The Boeing 747 is a wide-body commercial jet airliner and cargo aircraft, often referred to by its original nickname, Jumbo Jet. Its distinctive hump upper deck along a portion of the fuselage has made it one of the world's most recognizable aircraft, and it was the first wide-body airliner produced.
The Airbus A380 is a wide-body airliner manufactured by Airbus. It is the world's largest passenger airliner, and only full-length double-deck jet airliner ever produced. Airbus studies started in 1988, and the project was announced in 1990 to challenge the dominance of the Boeing 747 in the long-haul market.
