737800

The Boeing 737-800, often written 737-800, is a twin-engine, single-aisle jet airliner in Boeing's 737 Next Generation family. It is the most widely produced variant of the NG and was designed as the stretched successor to the 737-700 to offer higher capacity on short- to medium-range routes. The 737-800 first flew in 1997 and entered commercial service in 1998.

Powered by CFM56-7B engines, the aircraft incorporates an upgraded wing and tail design, improved avionics, and optional blended winglets that enhance fuel efficiency. Typical seating is around 162 to 189 passengers, depending on configuration, with a range of roughly 2,900 to 3,300 nautical miles.

Operators around the world use the 737-800 for a wide variety of routes, especially on dense domestic networks and low-cost carriers. It has been adopted by major airlines such as Ryanair, Southwest Airlines, easyJet, Turkish Airlines, Alaska Airlines, and Air China, among others. A dedicated freighter version, the 737-800BCF, completed conversions began in the late 2010s, expanding its role in cargo transport.

Production of the 737-800 continued alongside other 737 Next Generation models until Boeing shifted emphasis to the 737 MAX family; the -800 remains in service with numerous operators and continues in some fleets as a workhorse of single-aisle air travel.
