Cessna Citation Longitude vs Gulfstream G280 vs Gulfstream G400

The Cessna Citation Longitude sits in the super‑midsize category, offering transcontinental capability with a typical range of about 3,500 nautical miles and seating commonly arranged for around 8 to 12 passengers, depending on the cabin layout. The Gulfstream G280 is also a super‑midsize jet, generally comparable in mission profile but with longer legs, typically around 3,600 to 3,900 nautical miles, and passenger seating usually in the 8 to 10 range, again varying by configuration. The Gulfstream G400 moves up into the large‑cabin/long‑range category, designed for longer nonstop missions than either super‑midsize option, with published range around 4,000+ nautical miles and typical seating often around 10 to 14 passengers. In practical terms, Longitude and G280 compete closely on size and capacity, with the G280 usually edging range, while the G400 targets a larger cabin experience and longer routes with higher typical passenger counts.
