Bombardier Challenger 650 vs Bombardier Global 8000 vs Gulfstream G280 vs Gulfstream G400 vs Gulfstream G650er

The Bombardier Challenger 650 and Gulfstream G280 sit in the super-midsize category. The Challenger 650 typically carries about 8–12 passengers and offers roughly 4,000 nautical miles of range, while the G280 is similar in capacity (about 8–10) with slightly longer range around 3,600–3,900 nautical miles depending on conditions and configuration. Moving up, the Gulfstream G400 is a large-cabin, long-range jet, generally configured for about 10–14 passengers with an advertised range near 4,200 nautical miles. At the top end are the ultra-long-range, large-cabin aircraft. The Bombardier Global 8000 is positioned as an ultra-long-range flagship, commonly accommodating about 12–16 passengers with a published range around 8,000 nautical miles. The Gulfstream G650ER is also ultra-long-range, typically set up for about 11–18 passengers, with an advertised range of about 7,500 nautical miles. Overall, cabin size and range scale upward from the Challenger 650/G280 to the G400, then to the Global 8000 and G650ER, which prioritize intercontinental missions with larger cabins and higher passenger comfort.
