The Boeing 777 is a family of long-range wide-body twin-engine jet airliners developed and manufactured by Boeing Commercial Airplanes. The aircraft is capable of transporting up to 451 passengers.
The 777 is produced in two fuselage lengths as of 2018. The original 777-200 variant entered commercial service in 1995, followed by the extended-range 777-200ER in 1997. The stretched 777-300, which is 33.25 ft (10.1 m) longer, followed in 1998. They have since been collectively referred to as 777 Classics
The extended-range 777-300ER and ultra long-range 777-200LR variants entered service in 2004 and 2006 respectively.
The 777-200LR is one of the world’s longest-range airliners, able to fly more than halfway around the globe and holds the record for the longest distance flown non-stop by a commercial aircraft. In November 2013, Boeing announced the development of the third-generation of the 777, the 777X, consisting of the 777-8 and 777-9 variants. The 777X features composite wings with folding wingtips and General Electric GE9X engines plus further technologies developed for the Boeing 787 Dreamliner, and is scheduled to enter service by 2020.
The 777 first entered commercial service with United Airlines on June 7, 1995. The 777 has received more orders than any other wide-body airliner; as of May 2019, more than 60 customers had placed orders for 2,033 aircraft of all variants, with 1,598 delivered. The most common and successful variant is the 777-300ER with 806 delivered and 842 orders; Emirates operates the largest 777 fleet, with 163 passenger and freighter aircraft as of July 2018.
The 777 ranks as one of Boeing’s best-selling models; by 2018 it had become the most-produced Boeing wide-body jet, surpassing the Boeing 747. Airlines have acquired the type as a comparatively fuel-efficient alternative to other wide-body jets and have increasingly deployed the aircraft on long-haul transoceanic routes. Direct market competitors include the Airbus A330-300, the Airbus A350 XWB, and the out-of-production A340 and McDonnell Douglas MD-11. The Boeing 787 Dreamliner, which entered service in 2011, shares some design features with the new 777X models.
