Bombardier Challenger 650 vs Bombardier Global 6500 vs Gulfstream G600 vs Gulfstream G650er

The Bombardier Challenger 650 is a large-cabin business jet optimized for regional and transcontinental missions rather than true ultra-long-range flying. It typically carries about 8 to 12 passengers in comfort (with higher maximum layouts possible) and offers roughly 4,000 nautical miles of range, making it well suited to North America and many North Atlantic city pairs with favorable winds. The Bombardier Global 6500 moves into the ultra-long-range category, generally configured for around 12 to 16 passengers, with about 6,600 nautical miles of range, enabling longer intercontinental routes and more nonstop flexibility. The Gulfstream G600 sits in the long-range/large-cabin class between super-midsize and the largest ultra-long-range jets. It commonly seats about 10 to 16 passengers and provides roughly 6,600 nautical miles of range, similar in headline distance to the Global 6500 but in a different cabin and performance package. The Gulfstream G650ER is a flagship ultra-long-range aircraft, typically configured for about 11 to 18 passengers, with around 7,500 nautical miles of range, offering the greatest nonstop reach of the four.
