Bombardier Global 5500 vs Dassault Falcon 10x vs Dassault Falcon 6x vs Gulfstream G400

All four are large-cabin business jets, but they span different capability tiers. The Bombardier Global 5500 is a long-range large-cabin jet aimed at intercontinental missions, offering a range of about 5,900 nautical miles and typically seating around 8–12 passengers (with higher-density layouts possible). Dassault’s Falcon 6X is a newer large-cabin, long-range twin designed for comfort and efficiency, with roughly 5,500 nautical miles of range and a typical capacity of about 10–14 passengers. The Gulfstream G400 sits in the large-cabin long-range segment as well, with a published range around 4,200 nautical miles and typical seating near 10–12 passengers, making it more “transcontinental-plus” than true ultra-long-range. The Dassault Falcon 10X is the step-up ultra-long-range flagship in this group, targeting the longest missions with about 7,500 nautical miles of range and generally accommodating roughly 10–16 passengers depending on layout. In short, the 10X leads on range and cabin scale, the Global 5500 and 6X cluster in the intercontinental tier, and the G400 emphasizes range at the lower end of this set.
