The Airbus A380 is a double-deck, wide-body, four-engine jet airliner manufactured by European manufacturer Airbus. It is the world's largest passenger airliner, and the airports at which it operates have upgraded facilities to accommodate it. It was initially named Airbus A3XX and designed to challenge Boeing's monopoly in the large-aircraft market. The A380 made its first flight on April 27th, 2005 and entered commercial service in October 25th, 2007 with Singapore Airlines.
The A380's upper deck extends along the entire length of the fuselage, with a width equivalent to a wide-body aircraft. This gives the A380-800's cabin 5,920 square feet (550 m2) of usable floor space, 40% more than the next largest airliner, the Boeing 747-8, and provides seating for 525 people in a typical three-class configuration or up to 853 people in an all-economy class configuration. The A380-800 has a design range of 8,500 nautical miles (15,742 kilometers), serving the second and third longest non-stop scheduled flights (as of February 2017) in the world, and a cruising speed of Mach 0.85 (about 900 km/h, 560 mph or 490 kt at cruising altitude).
As of February 2017, Airbus had received 317 firm orders and delivered 208 aircraft; Emirates is the biggest A380 customer with 142 ordered of which 93 have been delivered.
