Commercial aircraft are commonly compared by category, range, and passenger capacity because these factors largely determine what routes they can fly and how airlines deploy them. Regional aircraft, including regional jets and turboprops, typically carry about 30 to 90 passengers and are optimized for short-range service, often a few hundred to roughly 1,500 nautical miles, linking smaller cities to major hubs with lower trip costs and good frequency. Narrow-body airliners, the workhorses of domestic and short-to-medium international travel, usually seat around 120 to 240 passengers and fly roughly 2,500 to 4,000 nautical miles, making them suitable for high-demand short-haul routes and many transcontinental flights. Wide-body airliners are designed for long-haul operations, generally carrying about 250 to 450+ passengers with ranges often around 6,000 to 8,500 nautical miles, enabling intercontinental service and high-capacity hub-to-hub markets. At the top end, very large wide-bodies prioritize maximum capacity—often 500+ passengers—though their practical use depends on airport constraints, demand concentration, and airline network strategy.
