Boeing 737-800

The Boeing 737 Next Generation, commonly abbreviated as 737NG, or 737 Next Gen jet airplanes are narrow-body aircraft powered by two engines and produced by Boeing Commercial Airplanes. Launched in 1993 as the third generation derivative of the Boeing 737, it has been produced since 1997 and is an upgrade of the 737 Classic (−300/-400/-500) series. It features a redesigned wing with a larger area, a wider wingspan, greater fuel capacity and higher maximum takeoff weights (MTOW). It is equipped with CFM International CFM56-7 series engines, a glass cockpit, and features upgraded and redesigned interior configurations.

It has a longer range and larger variants than its predecessor: the series includes four models, the −600/-700/-800/-900, seating between 108 and 215 passengers. The 737NG's primary competition is with the Airbus A320 family. As of November 30, 2019, a total of 7,092 Boeing 737NG aircraft have been ordered, of which 7,046 have been delivered, with remaining orders for the -700W, -800, and -800A variants. Boeing stopped assembling passenger 737NGs in 2019, but made the final deliveries in January 2020. It is superseded by the fourth generation Boeing 737 MAX, introduced in 2017.
