Boeing Bbj 777x vs Bombardier Global 8000 vs Dassault Falcon 10x vs Gulfstream G650er vs Gulfstream G800

In category, the Boeing BBJ 777X is a VIP widebody airliner conversion, vastly larger than the others, which are purpose-built ultra-long-range business jets. For range, the BBJ 777X is designed for true intercontinental missions (often cited around the low‑11,000‑nm class, depending on variant and configuration), while the newest large-cabin jets cluster near the top of the business-aviation market: Bombardier’s Global 8000 targets about 8,000 nm, Dassault’s Falcon 10X is in the ~7,500‑nm class, Gulfstream’s G800 targets about 8,000 nm, and the G650ER is roughly 7,500 nm. Passenger capacity differs most. The BBJ 777X can be configured for dozens of passengers with expansive living, dining, and office zones, far beyond any business jet. The Global 8000, Falcon 10X, G650ER, and G800 typically seat around 12–19 passengers in executive layouts, with maximum certified capacities generally in the high teens (varying by interior and certification choices). Overall, the BBJ 777X prioritizes space and headcount, while the others emphasize nonstop range, speed, and large-cabin comfort for smaller groups.
