Gulfstream G600 vs Gulfstream G650 vs Gulfstream G650er

Both the Gulfstream G600 and Gulfstream G650ER sit in the large-cabin, long-range business jet segment, but they serve slightly different missions. The G600 is typically positioned as a large-cabin, long-range jet optimized for a balance of range, runway flexibility, and operating efficiency, making it well suited for transcontinental and many intercontinental routes. The G650ER is Gulfstream’s ultra-long-range flagship-class option, aimed at the longest nonstop city pairs and maximum time aloft with fewer fuel stops. In range terms, the G600 is generally advertised around 6,600 nautical miles, enabling long intercontinental trips, while the G650ER stretches further to about 7,500 nautical miles, giving it a meaningful advantage for the longest nonstop missions. For passenger capacity, both can be configured in multiple layouts depending on operator needs. In typical executive arrangements, the G600 often seats roughly 13 to 15 passengers, while the G650ER commonly seats about 14 to 18, with maximum certified capacities higher for both in higher-density configurations.
