Dassault Falcon 10x vs Dassault Falcon 8x vs Gulfstream G600 vs Gulfstream G800 1

The Dassault Falcon 10X and Gulfstream G800 sit in the ultra-long-range, flagship category, while the Dassault Falcon 8X and Gulfstream G600 are large-cabin long-range jets one tier down in capability. The Falcon 10X is designed for about 7,500 nautical miles of range and typically accommodates roughly 10–19 passengers depending on layout, emphasizing a very large cabin. The Falcon 8X offers around 6,450 nautical miles and is commonly configured for about 12–16 passengers. Gulfstream’s G600 targets the upper large-cabin segment with about 6,600 nautical miles of range and typical seating around 13–17 passengers. The G800 leads the group on range at about 8,000 nautical miles and generally carries about 12–19 passengers, optimized for very long missions. In short, the Falcon 8X and G600 compete closely on long-range missions with similar cabin capacities, while the Falcon 10X and especially the G800 push into the longest-range category with larger, more flexible cabins.
