Cessna Citation Longitude vs Gulfstream G600 vs Gulfstream G650er

The Cessna Citation Longitude is typically positioned in the super-midsize category, optimized for efficient long domestic and some transatlantic missions. It offers a published range around 3,500 nautical miles and commonly seats about 8 to 12 passengers, depending on configuration, emphasizing comfort and operating economics rather than maximum intercontinental reach. The Gulfstream G600 is a large-cabin, long-range business jet aimed at true intercontinental capability with strong runway performance and a spacious cabin. Its published range is roughly 6,600 nautical miles, and typical seating is about 12 to 16 passengers, with layouts varying from high-comfort executive arrangements to higher-density configurations. The Gulfstream G650ER sits in the ultra-long-range, flagship-class category, designed for the longest nonstop city pairs and a very large, premium cabin. It offers a published range around 7,500 nautical miles and usually accommodates about 14 to 18 passengers, again depending on how the cabin is appointed.
