Boeing Bbj 777x vs Boeing Bbj 787 vs Gulfstream G700

By category, the Boeing BBJ 777X and BBJ 787 are ultra-long-range VIP airliners (widebody, multi-zone cabin “flying mansion” concepts), while the Gulfstream G700 is a purpose-built ultra-long-range business jet optimized for high-speed, high-altitude private operations and access to more airports. On range, the BBJ 777X is positioned as the longest-legged option, typically cited around 11,000 nautical miles depending on configuration and payload, enabling near-global nonstop missions. The BBJ 787 is also ultra-long-range, commonly advertised around 9,800–10,000 nautical miles, still covering most city pairs nonstop but generally trailing the 777X. The Gulfstream G700 offers roughly 7,500 nautical miles (varies by speed and reserves), which is exceptional for a business jet but shorter than the widebody BBJs. On passenger capacity, both BBJ airliners can be configured for very high counts but are usually outfitted for luxury with far fewer: the BBJ 777X can support the largest VIP layouts (often dozens to well over 100, depending on density), the BBJ 787 somewhat less but still far above typical business jets. The G700 is typically arranged for about 10–19 passengers, with maximum seating usually in the low-to-mid 20s.
