Bombardier Challenger 650 vs Bombardier Global 5500 vs Dassault Falcon 2000lxs vs Gulfstream G280 vs Gulfstream G400

The Bombardier Challenger 650 and Gulfstream G280 are typically categorized as large-cabin (super-midsize–leaning) business jets, while the Bombardier Global 5500 and Gulfstream G400 are long-range, ultra-long-range–oriented large-cabin jets; the Dassault Falcon 2000LXS sits in the large-cabin category with a focus on balanced range and airport flexibility. In range, the Challenger 650 is the shortest of the group at roughly 4,000 nm-class capability, suited to transcontinental missions. The Falcon 2000LXS and G280 generally step up from there, commonly quoted around the mid‑4,000 nm class, enabling longer city pairs with comfortable reserves. The Global 5500 and G400 extend into true long-range missions, typically around the 5,500–6,000+ nm class depending on configuration and assumptions, supporting many intercontinental routes. For passenger capacity, all are commonly flown with about 8–12 passengers in typical executive layouts; maximum certified seating is generally higher on paper, with the larger-cabin long-range models (Global 5500 and G400) usually offering the most space and flexibility for 12–16 passengers in denser configurations.
