Dassault Falcon 6x vs Gulfstream G500 vs Gulfstream G600 vs Gulfstream G650er

The Dassault Falcon 6X, Gulfstream G500, Gulfstream G600, and Gulfstream G650ER all sit in the large-cabin, long-range business jet category, but they span different tiers. The Falcon 6X and Gulfstream G500 are typically positioned as large-cabin, long-range jets, suitable for transcontinental missions and many intercontinental routes, with the 6X emphasizing a very wide, tall cabin and the G500 emphasizing speed and efficiency. The Gulfstream G600 moves up into the large-cabin, longer-range segment, offering more reach than the G500 and generally more flexibility for nonstop city pairs that push deeper into intercontinental travel. The Gulfstream G650ER is the flagship here: an ultra-long-range, large-cabin jet designed for the longest nonstop missions among the four. In passenger terms, all can be configured for roughly 12 to 19 passengers depending on layout, but typical executive configurations cluster around 12 to 16, with the G650ER often arranged to carry larger groups while still preserving range. Range generally increases from G500 and 6X, to G600, and highest with the G650ER.
