Airbus Acj319 vs Boeing Bbj Max 8 vs Gulfstream G400
The Airbus ACJ320 and Boeing BBJ MAX 8 are “VIP airliner” conversions in the large-cabin category, designed to provide a wide-body-style cabin experience from single-aisle airframes, while the Gulfstream G400 is a purpose-built large-cabin business jet focused on efficiency and airport flexibility. In range terms, the BBJ MAX 8 is generally positioned as the longest-legged of the two airliner-based options, with the ACJ320 also offering long intercontinental capability depending on tank and configuration choices; the G400 offers true long-range business-jet performance, typically shorter than the VIP airliners but still suitable for many transoceanic missions. Passenger capacity differs most by mission: ACJ320 and BBJ MAX 8 can be outfitted for very high headcounts in airline-style seating, but in VIP layouts they typically carry a few dozen with multiple lounges and bedrooms. The G400 seats fewer overall, usually in the low-to-mid teens in standard executive arrangements, prioritizing comfort, baggage, and nonstop range over maximum headcount.
