Cessna Citation Latitude vs Cessna Citation Longitude vs Cessna Citation Sovereign vs Gulfstream G400 vs Gulfstream G650er

The Cessna Citation Latitude and Longitude sit in the midsize-to-super-midsize business jet space, while the Citation Sovereign+ is a super-midsize jet optimized for efficient transcontinental missions. The Gulfstream G400 is a large-cabin, long-range jet, and the Gulfstream G650ER is an ultra-long-range, flagship large-cabin aircraft. In range terms, the Latitude is the shortest-legged of the group at roughly 2,700 nautical miles, suited to North America regional and some coast-to-coast flying. The Sovereign+ typically reaches about 3,200 nautical miles, and the Longitude extends further to around 3,500 nautical miles, making it the strongest performer among these Citations for longer nonstop city pairs. Stepping up, the Gulfstream G400 targets true long-range capability at about 4,200 nautical miles, while the G650ER is in a different class at roughly 7,500 nautical miles, enabling many intercontinental nonstop routes. Passenger capacity generally scales with cabin size: Latitude commonly carries about 8–9 passengers, Sovereign+ about 8–10, and Longitude about 8–12. The G400 often seats around 12–14, and the G650ER typically accommodates about 14–19 depending on layout.
