Airbus Acj350 vs Boeing Bbj 787 vs Bombardier Challenger 3500 vs Gulfstream G400

The Airbus ACJ350 and Boeing BBJ 787 sit in the ultra-long-range, widebody/VIP airliner category, offering intercontinental capability and the most cabin volume for large delegations. In typical VIP configurations, each can fly roughly 9,000–11,000+ nautical miles depending on variant and fit, and can be arranged for anywhere from a few dozen up to well over 50 passengers, with extensive private rooms and meeting/dining spaces. The Bombardier Challenger 3500 is a super-midsize business jet aimed at efficient regional and transcontinental missions. Its range is about 3,400 nautical miles, and it commonly carries 8–10 passengers in a business layout, with a smaller cabin optimized for productivity and cost-effective operations. The Gulfstream G400 is a large-cabin, long-range business jet positioned between super-midsize and ultra-long-range flagships. It targets around 4,000+ nautical miles of range and typically seats about 10–14 passengers, offering more space and nonstop flexibility than the Challenger 3500, but far less cabin volume and headcount capacity than ACJ350/BBJ 787.
