Cessna Citation Cj4 vs Gulfstream G400

The Cessna Citation CJ4 and Gulfstream G400 sit in very different business-jet categories. The CJ4 is a light jet optimized for efficient regional and transcontinental missions, typically used for owner-operators and small corporate trips. The Gulfstream G400 is a large-cabin jet designed for higher-end corporate and charter missions, emphasizing long-range capability and a more spacious cabin. In range, the CJ4 is suited to medium-to-long trips for its class, commonly covering roughly 2,000-plus nautical miles depending on conditions and configuration, making it practical for many U.S. coast-to-coast or similar missions with planning. The G400 is built for substantially longer legs, advertised around the 4,000-nautical-mile class, enabling many nonstop intercontinental routes. Passenger capacity also differs markedly. A CJ4 typically seats about 7 to 9 passengers in standard executive layouts. The G400 generally accommodates more, often around 10 to 14 passengers depending on cabin configuration, with greater comfort and amenities over longer durations.
