Dassault Falcon 7x vs Gulfstream G400

The Dassault Falcon 7X and Gulfstream G400 sit in the large-cabin, long-range business jet category, but they emphasize slightly different missions. The Falcon 7X is an established ultra-long-range tri-jet designed for intercontinental flying, with a published range around 5,950 nautical miles, making it well suited to very long nonstop routes and demanding airport conditions. It typically accommodates about 12 to 16 passengers depending on layout, with many operators configuring it around 12 to balance comfort and baggage space. The Gulfstream G400 is a newer large-cabin, long-range model positioned below Gulfstream’s flagship ultra-long-range aircraft. It is designed for transoceanic missions and efficient long-haul travel, with a stated range around 4,200 nautical miles. Typical seating is also in the roughly 10 to 12 passenger range, with higher-density configurations possible. In general, choose the Falcon 7X if maximum nonstop range is the priority, and the G400 if you want a modern Gulfstream cabin and performance optimized for slightly shorter long-range missions.
