Dassault Falcon 6x vs Gulfstream G500 vs Gulfstream G600

The Dassault Falcon 6X sits in the large-cabin, long-range business jet category and is often positioned as a high-comfort, long-haul platform. Its typical range is about 5,500 nautical miles, and it commonly accommodates around 12 to 16 passengers depending on cabin configuration. The Gulfstream G500 is in the large-cabin, long-range category as well, generally sized slightly below the G600 in capability. It offers a typical range of about 5,300 nautical miles and is usually arranged for roughly 12 to 16 passengers, with layouts varying by operator preference. The Gulfstream G600 is a step up within the same overall class, leaning toward the upper end of large-cabin, long-range performance. Its typical range is about 6,600 nautical miles, and it commonly carries around 12 to 17 passengers. In practical terms, the G600 emphasizes the longest reach, the G500 provides a slightly shorter-range alternative with a similar cabin class, and the Falcon 6X competes closely on long-range missions with an emphasis on cabin comfort and space.
