Cessna Citation Longitude vs Dassault Falcon 7x vs Gulfstream G650er vs Gulfstream G800 1

The Cessna Citation Longitude is a super‑midsize business jet aimed at shorter intercontinental missions, with roughly 3,500 nautical miles of range and typically seating about 8 to 12 passengers in a standard executive layout. The Dassault Falcon 7X steps up into the large‑cabin, long‑range category, offering around 5,900–6,000 nautical miles and commonly accommodating about 12 to 16 passengers. The Gulfstream G650ER is an ultra‑long‑range, large‑cabin flagship designed for true global missions, with about 7,500 nautical miles of range and typical seating near 14 to 19 passengers depending on configuration. The Gulfstream G800 is the newer ultra‑long‑range offering and extends capability further, with a published range around 8,000 nautical miles and similar large‑cabin capacity, often configured for roughly 14 to 19 passengers. In short, Longitude prioritizes efficiency in the super‑midsize segment, the 7X covers long‑range large‑cabin needs, and the G650ER and G800 target the longest nonstop routes with the biggest cabins and highest endurance.
