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

The Bombardier Challenger 650 and Gulfstream G280 sit in the super-midsize class, while the Bombardier Global 6500 and Gulfstream G650ER are large-cabin, ultra-long-range jets. For range, the Challenger 650 is typically around 4,000 nautical miles, suitable for many transcontinental U.S. or shorter transatlantic missions. The G280 is similar but generally longer-legged at roughly 3,600–3,900 nautical miles. Stepping up, the Global 6500 offers true intercontinental capability at about 6,600 nautical miles, enabling routes like New York–Moscow or Los Angeles–London under favorable conditions. The G650ER is the longest-range option here at about 7,500 nautical miles, aimed at missions such as New York–Hong Kong or Los Angeles–Sydney with fewer stops. In passenger capacity, the Challenger 650 commonly seats about 8–12 in a typical executive layout, and the G280 about 8–10. The Global 6500 usually accommodates roughly 12–16, while the G650ER is often configured for about 12–18, reflecting its larger cabin and mission profile.
