Beechcraft King Air 360 vs Beechcraft King Air 360er vs Cessna Citation Cj3 vs Cessna Citation Cj4 vs Cessna Citation Longitude

The Beechcraft King Air 360 and 360ER are twin‑turboprop business aircraft aimed at short to midrange missions with strong short‑field and lower‑speed airport access. The King Air 360 typically offers roughly 1,800 nautical miles of range and seats about 6–9 passengers depending on layout. The King Air 360ER is the extended‑range variant, optimized for longer legs at the expense of some payload flexibility, with roughly 2,400 nautical miles of range and a similar typical seating band of about 6–9. The Cessna Citation CJ3+ and CJ4 are light jets; they fly faster and higher than the King Airs and are generally used for efficient point‑to‑point business travel. The CJ3+ typically ranges around 2,000 nautical miles with about 6–9 seats, while the CJ4 stretches to about 2,100+ nautical miles and often carries about 7–10. The Cessna Citation Longitude is a super‑midsize jet with a substantially larger cabin, longer legs, and higher comfort for teams, offering about 3,500 nautical miles of range and typically seating around 8–12 passengers.
