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

The Bombardier Challenger 650 and Gulfstream G280 are typically grouped in the super‑midsize category, while the Bombardier Global 5500 and Gulfstream G400 sit in the large‑cabin/long‑range class. In range, the Challenger 650 is the shortest of the four at roughly 4,000 nautical miles, suitable for many transcontinental and some North Atlantic missions. The G280 generally reaches farther, around 3,600–3,900 nautical miles depending on assumptions, giving it strong U.S. coast‑to‑coast capability with good reserves. Stepping up, the Global 5500 is a true long‑range aircraft at about 5,900 nautical miles, enabling routes such as North America to much of Europe and deeper South America. The G400 is also long‑range, commonly cited around 4,200–4,800 nautical miles, positioned between the super‑midsize pair and the Global 5500. For passenger capacity, typical executive layouts place the Challenger 650 and G280 around 8–10 passengers, while the Global 5500 and G400 often seat about 10–14, with maximum certified counts higher depending on configuration.
