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

The Bombardier Challenger 650 is a large-cabin business jet aimed at comfortable regional and transcontinental missions, typically carrying about 8–12 passengers (up to around 12–15 depending on configuration) with a range of roughly 4,000 nautical miles. The Gulfstream G280 sits in the super‑midsize category, generally optimized for 8–10 passengers, with a similar but slightly longer typical range around 3,600–3,800 nautical miles, emphasizing efficient long legs in a smaller cabin than the large‑cabin jets. Stepping up in size and capability, the Bombardier Global 5500 is a long‑range large‑cabin jet, commonly configured for about 10–16 passengers, with range around 5,900 nautical miles, targeting intercontinental missions with more space and amenities. The Dassault Falcon 6X is also a long‑range large‑cabin jet, typically accommodating about 12–16 passengers, with range around 5,500 nautical miles; it emphasizes a very wide, tall cabin and long‑haul comfort comparable to the Global 5500, while the Challenger 650 and G280 serve shorter missions with smaller overall cabin volume.
