Aircraft are often compared first by category: regional aircraft, narrow-body jets, wide-body jets, and very large aircraft. Regional types, including turboprops and small regional jets, prioritize short-haul efficiency and frequent service, typically covering a few hundred to about 1,500 nautical miles and carrying roughly 30 to 90 passengers. Narrow-body jets are the mainstay of domestic and short-to-medium international routes, generally flying about 1,500 to 4,000 nautical miles with typical seating from about 120 to 240 passengers depending on layout. Wide-body jets are built for long-haul travel, offering greater fuel capacity, cargo volume, and twin-aisle comfort; they commonly operate around 4,000 to 8,500 nautical miles and carry about 250 to 400 passengers, with higher capacities in dense configurations. Very large aircraft sit at the top end, designed for high-demand hub-to-hub routes; they can exceed 400 passengers and may still achieve long-range missions, but are most efficient when consistently filled on major trunk routes.
