Dassault Falcon 900lx vs Gulfstream G400 vs Gulfstream G650er

The Dassault Falcon 900LX is typically categorized as a large-cabin trijet, valued for strong short-field performance and operational flexibility. Its range is roughly in the 4,700–4,900 nautical mile class, which generally supports transcontinental U.S. missions and many North Atlantic city pairs with favorable winds. Passenger capacity is commonly configured around 12–14, though layouts vary by operator. The Gulfstream G400 sits in the large-cabin segment below the ultra-long-range flagships, positioned for longer nonstop missions than many traditional large-cabin jets. Its advertised range is about 4,200 nautical miles, and typical seating is about 10–12 passengers, with maximum layouts higher depending on certification and interior choices. The Gulfstream G650ER is an ultra-long-range, ultra-large-cabin jet designed for true intercontinental flying. Its range is about 7,500 nautical miles, enabling many nonstop pairings such as New York to Hong Kong or Los Angeles to Sydney under appropriate conditions. Typical passenger capacity is around 14–16, with higher-density configurations possible.
