Bombardier Challenger 650 vs Bombardier Global 5500 vs Dassault Falcon 6x vs Gulfstream G280 vs Gulfstream G500

The Bombardier Challenger 650 and Gulfstream G280 sit in the super-midsize category, typically carrying about 8–10 passengers. The Challenger 650 is optimized for comfort and short-to-mid intercontinental missions with roughly 4,000 nm of range, while the G280 is a faster, long-legged super-midsize with about 3,600–3,900 nm, often configured for 8–10. The Bombardier Global 5500, Dassault Falcon 6X, and Gulfstream G500 are large-cabin, long-range jets designed for true intercontinental flying and generally accommodating around 10–16 passengers depending on layout. The Global 5500 offers about 5,900 nm, balancing range and a spacious cabin. The Falcon 6X emphasizes a very wide, tall cabin and long reach at roughly 5,500 nm. The Gulfstream G500 is similarly positioned as a large-cabin long-range aircraft with about 5,200–5,300 nm, typically arranged for around 12–14 passengers. Overall, the step up from Challenger 650/G280 to Global 5500/6X/G500 brings notably more cabin volume and longer nonstop city-pair capability.
