Bombardier Challenger 650 vs Bombardier Global 5500 vs Bombardier Global 6500 vs Gulfstream G280 vs Gulfstream G650er

The Bombardier Challenger 650 is a large-cabin business jet best suited to North American missions, typically offering about 7–9 passengers and roughly 4,000 nautical miles of range. Moving up in class, the Gulfstream G280 is a super‑midsize jet with similar passenger counts (about 8–10) but longer legs, around 3,600–3,900 nautical miles, depending on configuration. The Bombardier Global 5500 and Global 6500 are true ultra‑long‑range, large‑cabin jets; both generally carry about 10–13 passengers, with the 5500 around 5,900 nautical miles and the 6500 around 6,600 nautical miles, enabling many intercontinental city pairs. At the top end, the Gulfstream G650ER is an ultra‑long‑range flagship, typically configured for about 12–16 passengers and capable of roughly 7,500 nautical miles, making it the strongest option here for the longest nonstop routes and highest overall performance in the group.
