Bombardier Challenger 650 vs Bombardier Global 5500 vs Dassault Falcon 2000lxs vs Dassault Falcon 6x vs Gulfstream G500

The Challenger 650 and Falcon 2000LXS sit in the large-cabin, “super-midsize to large” segment, typically used for transcontinental missions rather than true ultra-long-haul. The Challenger 650 is commonly quoted around 4,000 nautical miles of range and is usually configured for about 8–12 passengers (with higher maximums possible), while the Falcon 2000LXS is similar in cabin class with roughly low-to-mid 4,000-nm capability and typical seating around 8–10. Stepping up, the Global 5500 and Gulfstream G500 are in the large-cabin, long-range class, aimed at longer city pairs and higher-speed cruise profiles; both are generally cited around the 5,200–5,300-nm range bracket with typical configurations around 10–13 passengers. At the top of this group, the Falcon 6X is an ultra-long-range, wide-cabin aircraft, generally advertised around 5,500 nm and often arranged for roughly 12–16 passengers, emphasizing cabin width and comfort on longer sectors.
