The Boeing 737-700 is a member of the Next Generation (NG) family of the popular Boeing 737 short-to-medium-range twin-engine narrow-body airliner. First delivered in 1997, it was designed as the direct replacement for the classic 737-300, offering improved fuel efficiency, greater range, and enhanced avionics. Typically seating between 126 and 149 passengers in a two-class configuration, the 737-700 serves as a versatile workhorse for airlines worldwide, well-suited for both domestic and regional routes where its capacity and operational efficiency are highly valued.
