The Boeing 737-700 is a short-to-medium-range, narrow-body airliner that belongs to the 737 Next Generation (NG) family. Designed to replace the earlier 737-300, the -700 introduced improved aerodynamics, advanced avionics, a new wing design, and greater fuel efficiency. It first entered service in 1998 with Southwest Airlines as the launch customer.

As the direct successor to the 737-300, the 737-700 retained seating capacity for around 130 passengers while offering increased range and performance. It became a popular choice for airlines seeking a flexible and efficient aircraft for regional and transcontinental routes.
