Dassault Falcon 7x vs Dassault Falcon 8x vs Dassault Falcon 900lx vs Gulfstream G600

The Dassault Falcon 7X and 8X are long‑range, large‑cabin trijets aimed at intercontinental missions. The 7X typically offers about 5,950 nautical miles of range and seats roughly 12–16 passengers in common executive layouts. The Falcon 8X is the newer, slightly stretched evolution, generally around 6,450 nautical miles of range with similar typical seating (about 12–16), but with more flexibility in cabin zoning and improved efficiency. The Dassault Falcon 900LX sits a step down as a long‑range, large‑cabin trijet optimized for slightly shorter missions, typically around 4,750 nautical miles, with usual seating in the 12–14 passenger range (higher-density configurations can be more). The Gulfstream G600 is a long‑range, large‑cabin twinjet positioned closer to the 7X/8X class, typically around 6,600 nautical miles of range, with common seating about 12–16 passengers. In broad terms, 900LX prioritizes “long” range, while 7X, 8X, and G600 target “ultra‑long” range, with the G600 and 8X generally leading on published range.
