Beechcraft King Air 300 vs Beechcraft King Air 350
The Beechcraft King Air 300 and King Air 350 represent two generations of the same essential mission: a pressurized turboprop twin for owner-pilots and charter operators who want turbine reliability and high-altitude routing without the price of a jet. The King Air 300 (from 1983) uses Pratt & Whitney PT6A-60A engines for 320-knot cruise at FL310 — the highest-performance variant in the original King Air B200 series family. The King Air 350 (1990) stretched the fuselage again, added winglets, and used the same PT6A-60A engines but in a package that carries more passengers (up to eleven), further, with more comfort. The cross-shop is whether the 350's size premium is worth the price premium.

Which Should You Buy: Beechcraft King Air 300 or Beechcraft King Air 350?
Bottom line: Choose the King Air 300 for lower acquisition cost in the high-performance King Air family and a shorter fuselage that's operationally nimble at smaller airports. A King Air 300 at market price represents strong value for the speed, altitude, and reliability it delivers. Choose the King Air 350 when passenger capacity, range (approximately 1,806 nm vs. 1,571 nm for the 300), or the winglet efficiency benefits of the updated airframe define the mission. The 350's eleven-seat capacity serves charter operations and family operators that the 300's eight-seat configuration approaches less comfortably. Safety axis: both aircraft use the same PT6A-60A engines — identical turbine reliability and maintenance profile. The 350's winglets improve single-engine directional control margin at altitude, a genuine structural improvement that the 300 lacks. No other meaningful safety differential.
Pick the King Air 300 if…
- Budget matters — from $947,809 vs $1,952,250, you save ~$1,004,441.
- Lower operating cost — ~$1050/hr vs $1100/hr.
Pick the King Air 350 if…
- More seats — 11 vs 9.
- Longer range — 1806 nm vs 1700 nm.
- Newer design — production from 1990 vs 1984.
- More inventory — 50 listings vs 18.
