Cessna Citation Longitude vs Embraer Praetor 500 vs Embraer Praetor 600 vs Gulfstream G280 vs Gulfstream G650er

The Cessna Citation Longitude and Embraer Praetor 500 sit in the super-midsize category, while the Embraer Praetor 600 and Gulfstream G280 are typically positioned at the high end of super-midsize (often marketed as “large-cabin” capable in mission), and the Gulfstream G650ER is firmly an ultra-long-range, large-cabin flagship. In range, the Praetor 500 and Citation Longitude are broadly comparable for most transcontinental missions, with the Longitude generally around the 3,500 nautical mile class and the Praetor 500 around the 3,300 nautical mile class. The Praetor 600 and G280 step up to roughly the 3,900–4,000 nautical mile class, enabling longer city pairs with more margin. The G650ER is in a different league at roughly 7,500 nautical miles, targeting true intercontinental routes. Typical passenger capacity follows cabin size: Longitude and Praetor 500 usually seat about 8–9 in comfort, Praetor 600 and G280 commonly 9–10, and the G650ER typically 12–16 (with higher maximum configurations depending on layout).
