Bombardier Challenger 650 vs Bombardier Global 5500 vs Dassault Falcon 6x vs Embraer Praetor 600 vs Gulfstream G280 vs Gulfstream G500

The Bombardier Challenger 650 and Embraer Praetor 600 sit in the super‑midsize/large‑cabin crossover space, typically carrying about 8–12 passengers. The Challenger 650 offers a long‑range large‑cabin experience but with shorter reach (around 4,000 nm), while the Praetor 600 is a true super‑midsize with strong transcontinental capability (roughly 4,000+ nm) in a slightly smaller cabin. The Gulfstream G280 is also super‑midsize, usually configured for about 8–10 passengers, with range in the same general band (about 3,600–4,200 nm depending on mission). Stepping up, the Gulfstream G500 is a large‑cabin, long‑range jet, commonly 10–13 passengers, with roughly 5,000+ nm class range. At the high end, the Bombardier Global 5500 and Dassault Falcon 6X are large‑cabin, long‑range aircraft aimed at intercontinental missions, typically 12–16 passengers. The Global 5500 is around the 5,900 nm class, while the Falcon 6X is roughly 5,500 nm, emphasizing a very wide, tall cabin.
