Cessna Citation Cj3 vs Cessna Citation Cj4 vs Beechcraft Kingair 350er

The Cessna Citation CJ3+ and CJ4 are both light jets, while the Beechcraft King Air 350ER is a twin‑turboprop. In category terms, the CJ3+ is a smaller light jet optimized for efficient short-to-medium business missions, the CJ4 is a stretched, higher-performance light jet with more capability, and the 350ER is a larger, rugged turboprop suited to shorter runways and flexible operations, including special-mission profiles. For range, the CJ4 generally offers the longest legs of the three (around 2,100+ nautical miles), the CJ3+ is typically next (around 2,000 nautical miles), and the King Air 350ER is comparable but often a bit lower in typical passenger configurations, with long-range capability depending heavily on fuel and payload tradeoffs. In passenger capacity, the CJ3+ commonly seats about 6 to 8, the CJ4 typically 8 to 10, and the King Air 350ER usually carries about 8 to 11, with the turboprop’s cabin and loading flexibility often favoring mixed passenger-and-gear missions.
