Bombardier Challenger 650 vs Bombardier Global 5500 vs Gulfstream G280 vs Gulfstream G400 vs Gulfstream G500

The Bombardier Challenger 650 is a large-cabin jet best suited to regional and transcontinental missions, offering roughly a 4,000‑nautical‑mile class range and typically seating about 8–12 passengers, with a focus on cabin comfort and operating economy. The Bombardier Global 5500 moves into the ultra‑long‑range category, reaching about 5,900 nautical miles and commonly configured for around 10–16 passengers, emphasizing longer nonstop city pairs and a larger, more flexible cabin. The Gulfstream G280 is a super‑mid/large‑cabin crossover with about a 3,600‑nautical‑mile class range and typically 8–10 passengers, optimized for efficient midsize operations with strong speed. The Gulfstream G400 is a long‑range large‑cabin aircraft positioned above the G280, with roughly a 4,200‑nautical‑mile class range and typical seating around 10–12. The Gulfstream G500 is a long‑range large‑cabin jet with about a 5,300‑nautical‑mile class range and usually 10–14 passengers, bridging the gap between large‑cabin comfort and near ultra‑long‑range capability.
