Dassault Falcon 7x vs Gulfstream G280 vs Gulfstream G400 vs Gulfstream G500

In category, the Dassault Falcon 7X and Gulfstream G500 sit in the large-cabin, long-range class, the Gulfstream G400 is a large-cabin jet positioned below the G500, and the Gulfstream G280 is a super‑midsize aircraft. For range, the Falcon 7X is typically cited around 5,950 nautical miles, making it comparable to the G500 at about 5,300 nautical miles and generally longer‑legged than the G400 at roughly 4,200 nautical miles; the G280 is shorter‑range than the large-cabin models at about 3,600 nautical miles. Passenger capacity follows cabin class: the G280 is commonly configured for about 8–10 passengers, while the Falcon 7X and G500 are typically arranged for about 10–14 passengers depending on layout. The G400 generally lands in a similar mid‑teens capability in typical configurations, often around 10–12, but can vary by interior. Overall, G280 emphasizes efficient super‑midsize missions, G400 targets large‑cabin regional/transcontinental flying, and Falcon 7X and G500 are geared toward longer intercontinental legs with more space.
