Dassault Falcon 10x vs Gulfstream G400

The Dassault Falcon 10X and Gulfstream G400 sit in different business-jet categories. The Falcon 10X is positioned as an ultra-long-range, large-cabin flagship, aimed at nonstop intercontinental missions. The Gulfstream G400 is a large-cabin, long-range jet, but a step below the top-tier “ultra-long-range” class, targeting long transoceanic trips with slightly less emphasis on maximum reach. On range, the Falcon 10X is designed for about 7,500 nautical miles, enabling city pairs such as New York to Hong Kong–type distances depending on conditions. The G400 is designed for about 4,200 nautical miles, supporting missions like New York to London–type routes, again dependent on winds, payload, and routing. For passenger capacity, both are typically configured for executive comfort rather than maximum seats. The Falcon 10X is commonly quoted around 8 to 19 passengers depending on layout, while the G400 is typically arranged for roughly 10 to 12 passengers, with maximum seating varying by configuration.
