Commercial aircraft generally fall into three broad categories: regional aircraft, narrow-body jets, and wide-body jets. Regional aircraft, including small turboprops and regional jets, are designed for shorter routes and smaller markets; they typically fly a few hundred to roughly 1,500 nautical miles and usually carry about 30 to 90 passengers. Narrow-body jets, commonly used for domestic and short-to-medium international service, balance efficiency with capacity; they often cover about 1,500 to 3,500 nautical miles and generally seat around 120 to 220 passengers depending on configuration. Wide-body jets serve long-haul and high-demand routes, offering greater range and passenger volume; many can fly roughly 4,000 to 8,000+ nautical miles and typically carry about 250 to 400+ passengers, with some high-density layouts exceeding that. In general, as aircraft move from regional to narrow-body to wide-body, both range and passenger capacity increase, while operating costs and airport/gate requirements also tend to rise.
