Bombardier Challenger 650 vs Bombardier Global 5500 vs Bombardier Global 6500 vs Dassault Falcon 6x vs Gulfstream G280

By category, the Bombardier Challenger 650 and Gulfstream G280 are super‑midsize business jets, while the Dassault Falcon 6X, Bombardier Global 5500, and Bombardier Global 6500 are large‑cabin, long‑range jets. In range terms, the Challenger 650 is best suited to medium‑to‑long missions at about 4,000 nm. The G280 typically offers slightly more reach in the ~3,600–3,800 nm class. Stepping up, the Falcon 6X is a true long‑range jet around 5,500 nm. The Global 5500 and Global 6500 extend farther, roughly 5,900 nm and 6,600 nm respectively, making the 6500 the longest‑range aircraft in this set. For passenger capacity, the Challenger 650 and G280 commonly seat about 8–10 in typical layouts (with higher maximums possible). The Falcon 6X, Global 5500, and Global 6500 generally carry around 10–13 passengers in typical configurations, with maximum certified seating usually higher depending on interior and operator choices.
