The Boeing 737-800 is a narrow-body, twin-engine commercial jet airliner developed by Boeing as part of the 737 Next Generation (NG) series. Introduced in the late 1990s, it is designed for short- to medium-haul routes and typically seats between 162 and 189 passengers, depending on cabin configuration.

The aircraft is powered by two CFM56 turbofan engines mounted under its wings and features a conventional flight control system supported by modern avionics. With a range of approximately 5,400 kilometers, the 737-800 is widely used for domestic and regional international flights.

Known for its operational reliability and efficiency, the Boeing 737-800 has become one of the most widely produced and flown commercial aircraft in the world. It is commonly operated by low-cost and full-service airlines alike. The model has gradually been supplemented by the newer 737 MAX series, which incorporates updated engines and aerodynamic improvements.
