Bombardier Challenger 650 vs Bombardier Global 5500 vs Dassault Falcon 6x vs Dassault Falcon 7x vs Dassault Falcon 900lx vs Gulfstream G400

All six are large-cabin business jets, but they span different missions. The Bombardier Challenger 650 is best viewed as a “large-cabin, shorter/medium-range” aircraft, typically seating about 8–12 passengers and offering roughly 4,000 nm class range, making it strong for transcontinental U.S. and shorter international sectors. Stepping up, the Bombardier Global 5500 is an ultra-long-range jet, usually configured for about 10–16 passengers with roughly 5,900 nm range, aimed at longer intercontinental city pairs. Dassault’s Falcon 6X is a new large-cabin, long-range jet with a very wide cabin, commonly 12–16 passengers and about 5,500 nm range. The Falcon 7X and Falcon 900LX are established large-cabin, long-range trijets; the 7X typically carries about 12–16 with around 5,950 nm range, while the 900LX is usually 10–14 with about 4,750 nm range. The Gulfstream G400 is a new large-cabin, long-range twin, generally 10–16 passengers with about 4,200 nm range, positioned above super-midsize and below Gulfstream’s longest-range models.
