Bombardier Challenger 650 vs Bombardier Global 5500 vs Bombardier Global 6500 vs Gulfstream G500 vs Gulfstream G600

The Bombardier Challenger 650 is a large-cabin business jet optimized for regional and transcontinental missions; it typically carries about 8–12 passengers and offers roughly 4,000 nautical miles of range. Moving up to the ultra‑long‑range class, the Bombardier Global 5500 and Global 6500 provide substantially more cabin space and endurance, generally seating around 10–16 passengers; the Global 5500 is around the 5,900‑nautical‑mile range class, while the Global 6500 extends to about 6,600 nautical miles. Gulfstream’s G500 and G600 sit in the large- to super‑midsize/long‑range category, emphasizing speed and high-altitude performance with typical seating near 10–15 passengers; the G500 is roughly a 5,300‑nautical‑mile airplane, and the G600 steps up to about 6,600 nautical miles. In practical terms, the Challenger 650 suits shorter long‑haul trips with fewer passengers, the Global 5500/G500 target long-range flexibility, and the Global 6500/G600 are the strongest options here for true intercontinental range with larger cabins.
