The largest passenger airplanes seat in the range of approximately 500 passengers, although a couple have much larger single-class seating capacities. The largest airplanes include three or four engines and are capable of flying at service ceilings of 35,000 feet or above. Among the biggest are: the Airbus 8380-800, Boeing 777-300, Boeing 747-400, Airbus A340-600 and Boeing 747-8 Intercontinental.
Airbus and Boeing are the only manufacturers of the 10 biggest passenger airplanes in the world, with one sole exception, the Russian Ilyushin 96-400, which is manufactured by the Voronezh Aircraft Production Association and ranks as the ninth largest passenger airplane in service, as of 2015. The Ilyushin entered into service with the airline Emirates in 2002 and runs on four RR Trent 500 engines, with a take-off thrust of 35,274lb each. It seats 436 passengers in single-class configuration, making it somewhat smaller than the largest planes manufactured by Boeing and Airbus.
The largest plane in service as of 2015 is the Airbus 8380-800. It has a maximum single-class seating capacity of 853 passengers and can accommodate up to 525 passengers in the three-class seating configuration. Known as the Superjumbo, the main cabin has two decks, and the plane is powered either by four Rolls-Royce Trent 900 engines or four Engine Alliance GP7200 engines.
