Airbus Acj320 vs Airbus Acj350 vs Boeing Bbj 777x vs Boeing Bbj 787 vs Bombardier Global 8000 vs Gulfstream G700

By category, the Airbus ACJ330neo, Airbus ACJ350, Boeing BBJ 777X, and Boeing BBJ 787 are widebody VIP airliners designed for head‑of‑state or large corporate missions with true “flying residence” interiors, while the Bombardier Global 8000 and Gulfstream G700 are ultra‑long‑range business jets optimized for higher cruise efficiency and access to more airports. On range, the ACJ350 and BBJ 777X sit at the top tier, typically advertised around roughly 10,000–11,000+ nautical miles depending on configuration, with the BBJ 787 and ACJ330neo generally a step below but still capable of most intercontinental city pairs. The Global 8000 is among the longest‑range purpose‑built business jets at about 8,000 nautical miles, while the G700 is slightly shorter at roughly 7,500 nautical miles. On passenger capacity, the widebody VIP airliners can be configured for very large delegations, often anywhere from a few dozen up to well over 100 passengers depending on layout, whereas the Global 8000 and G700 typically seat about 12–19 in high‑comfort executive configurations, with maximum layouts around the high‑teens to low‑20s.
