Bombardier Global 5500 vs Bombardier Global 6500 vs Dassault Falcon 6x vs Dassault Falcon 7x vs Gulfstream G280 vs Gulfstream G400 vs Gulfstream G500 vs Gulfstream G600

All eight are large-cabin business jets, but they split into “super‑midsize” and “large/ultra‑long‑range” roles. The Gulfstream G280 is the only super‑midsize option here, typically carrying about 8–10 passengers with roughly 3,600 nautical miles of range. The Bombardier Global 5500 and 6500, Dassault Falcon 6X and 7X, and Gulfstream G400/G500/G600 are large‑cabin, long‑range jets, generally configured for about 12–16 passengers depending on layout. On range, the Global 5500 and Falcon 6X sit around the low‑5,000‑nautical‑mile class, while the Global 6500 and Falcon 7X step up into the mid‑ to high‑5,000‑nautical‑mile class (the 7X is often cited around 5,950 nm). Gulfstream’s G400 is roughly in the low‑4,000‑nautical‑mile class, the G500 around 5,300 nm, and the G600 around 6,600 nm, making the G600 the longest‑legged of this group. In general, cabin and payload flexibility tend to increase as you move from G280/G400 toward G600 and Global 6500.
