Bombardier Challenger 650 vs Bombardier Global 5500 vs Gulfstream G280

The Bombardier Challenger 650 and Gulfstream G280 are typically grouped as super‑midsize business jets, while the Bombardier Global 5500 is a larger, long‑range jet in the large/ultra‑long‑range category. In range, the Challenger 650 is suited to transcontinental missions at roughly 4,000 nautical miles, the G280 generally reaches a bit farther at about 3,600–3,900 nautical miles depending on configuration and reserves, and the Global 5500 is in a different league with around 5,900 nautical miles, enabling more true intercontinental city pairs. For passenger capacity, all three commonly fly with 8–10 passengers in typical corporate layouts, but maximum certified seating differs: the Challenger 650 is usually up to about 12, the G280 up to about 10, and the Global 5500 up to about 16, with the larger cabin also offering more distinct living zones and more room for longer-duration comfort.
