The range of a Boeing 737 variant depends on a variety of factors, such as the specific model, engine type, and fuel capacity. Generally speaking, the range of a typical Boeing 737 variant is between 2,500 and 3,500 nautical miles (4,630 to 6,480 kilometers).
The range of the original 737-100 was around 1,540 nautical miles (2,850 kilometers), while the extended range 737-200 could fly up to 2,550 nautical miles (4,725 kilometers). The newer 737NG (Next Generation) series, which includes the 737-600, 737-700, 737-800, and 737-900, have ranges between 2,935 and 3,595 nautical miles (5,430 to 6,660 kilometers), depending on the model.
The latest variant of the 737, the 737 MAX, features improved engines and aerodynamics, which allow for greater fuel efficiency and an increased range. The 737 MAX 7 has a range of around 3,850 nautical miles (7,130 kilometers), while the 737 MAX 8 and 737 MAX 9 have ranges of around 3,550 and 3,550-3,750 nautical miles (6,570 and 6,940-6,940 kilometers), respectively.
It’s worth noting that the range of a 737 variant can be affected by factors such as passenger and cargo load, wind conditions, and altitude, among other things. Airlines will typically consider these factors when planning routes and determining the range of their aircraft.
