Dassault Falcon 6x vs Gulfstream G280 vs Gulfstream G400 vs Gulfstream G500

The Dassault Falcon 6X and Gulfstream G400 and G500 sit in the large-cabin, long-range business jet category, while the Gulfstream G280 is best viewed as a super-midsize jet. In range, the G500 is typically the longest-legged of this group, suitable for many transcontinental and some intercontinental missions, while the Falcon 6X is also firmly long-range and close behind in mission capability. The G400 is positioned below the 6X and G500 on range, offering long-range performance but generally not matching the very longest missions those two can cover. The G280 has the shortest range here, though it remains capable for many U.S. coast-to-coast and similar missions depending on payload and winds. For passenger capacity, the Falcon 6X and G500 commonly carry the most in typical configurations, with generous cabin volume supporting higher-comfort layouts. The G400 is comparable but usually slightly less spacious than the largest two. The G280 generally seats fewer passengers, reflecting its smaller super-midsize cabin.
