Dassault Falcon 2000lxs vs Dassault Falcon 6x vs Gulfstream G400

The Dassault Falcon 2000LXS is best viewed as a super‑midsize business jet optimized for efficient regional-to-intercontinental missions. It typically seats around 8–10 passengers in a standard executive layout (with higher-density options available) and offers a range of roughly 4,000 nautical miles, making it well suited to transcontinental U.S. flying and many North Atlantic pairings with favorable conditions. The Dassault Falcon 6X steps up into the large‑cabin class with a noticeably wider, taller cabin and more long‑range capability. It commonly accommodates about 12–16 passengers depending on configuration and is designed for approximately 5,500 nautical miles of range, supporting longer nonstop intercontinental city pairs. The Gulfstream G400 also competes in the large‑cabin segment, positioned between super‑midsize and ultra‑long‑range offerings but with a strong emphasis on cabin comfort and speed. Typical seating is about 12–16 passengers, and its published range is about 4,200 nautical miles, prioritizing high-end large‑cabin travel on medium-to-long routes rather than the longest global missions.
