Cessna Citation Longitude vs Dassault Falcon 6x vs Gulfstream G600

The Cessna Citation Longitude is best viewed as a super-midsize business jet, while the Dassault Falcon 6X and Gulfstream G600 sit in the large-cabin, long-range category. In range terms, the Longitude typically offers about 3,500 nautical miles, making it well suited to transcontinental U.S. missions and many regional international routes. The Falcon 6X and G600 step up substantially, with roughly 5,500–6,000+ nautical miles depending on configuration and conditions, enabling more nonstop intercontinental city pairs. Passenger capacity follows the same pattern. The Longitude is commonly configured for around 8 to 12 passengers, balancing efficiency with a comfortable stand-up cabin for its class. The Falcon 6X and G600 are usually outfitted for roughly 12 to 16 passengers, with larger cabins that support more distinct living zones and longer-duration comfort, though real-world seating depends heavily on the chosen floorplan. Overall, Longitude emphasizes value and operating economics in a smaller long-range envelope, while the 6X and G600 prioritize cabin volume and true long-haul capability.
