Bombardier Global 5500 vs Dassault Falcon 6x vs Dassault Falcon 8x vs Gulfstream G500 vs Gulfstream G600

All five are large-cabin, long-range business jets, but they split into “ultra‑long‑range” and “long‑range” tiers. The Bombardier Global 5500 is an ultra‑long‑range jet, typically offering about 5,900 nm of range and seating commonly in the 12–16 passenger class depending on layout. Dassault’s Falcon 6X is a large‑cabin, long‑range jet with roughly 5,500 nm range and similar typical capacity around 12–16, emphasizing a very wide cabin. The Falcon 8X steps up to ultra‑long‑range capability at about 6,450 nm, again generally configured for roughly 12–16, with strong long-haul flexibility. Gulfstream’s G500 sits in the large‑cabin, long‑range category at around 5,300 nm and is usually arranged for about 12–16. The Gulfstream G600 moves into the ultra‑long‑range tier at about 6,600 nm, with typical configurations also around 12–16, and is often compared most directly with the longest‑range options here.
