Airbus Acj Twotwenty vs Airbus Acj350 vs Boeing Bbj 777x vs Boeing Bbj 787 vs Boeing Bbj Max 8 vs Gulfstream G650er

By category, the Airbus ACJ TwoTwenty and Boeing BBJ 737 MAX are “large-cabin narrowbody” corporate airliners, while the Airbus ACJ350 and the Boeing BBJ 787 and BBJ 777X are “VIP widebody” platforms aimed at heads-of-state and ultra–long-range private travel. The Gulfstream G650ER is a purpose-built long-range business jet rather than an airliner conversion. On range, the G650ER and ACJ350 sit among the longest-legged options, typically around the 7,500–8,000+ nautical mile class depending on fit and mission. The BBJ 787 is similarly ultra–long-range, commonly cited around ~9,000+ nm. The BBJ 777X concept targets even greater intercontinental reach, often discussed in the ~10,000+ nm bracket, though final performance depends on variant and completion. The ACJ TwoTwenty and BBJ 737 MAX offer long-range corporate missions but generally less than the widebodies, roughly in the ~5,500–6,700 nm class. For passenger capacity, the G650ER is typically arranged for roughly 12–19. The ACJ TwoTwenty often supports about 18–50. The BBJ 737 MAX usually accommodates about 25–50+. Widebodies (ACJ350, BBJ 787, BBJ 777X) can be configured from a few dozen up to well over 100 in high-density VIP layouts.
