King Air 350
The Beechcraft King Air 350 is a pressurized twin-engine turboprop seating nine passengers at 312 knots with a range of 1,806 nautical miles and a 35,000-foot service ceiling. Against turboprop category averages, it runs significantly faster (312 vs 259 ktas avg) and farther (1,806 vs 1,374nm avg). The 19.2-foot cabin is 4.5 feet wide and 4.8 feet tall — narrower than the category average of 5.0 feet but longer than most competing turboprops, with Wi-Fi and a belted lavatory.
The US Part 135 fleet of 93 aircraft is among the most concentrated of any type in the database. Wheels Up Private Jets manages 31 aircraft, West Coast Aviation Services 13, and Advanced Air Charters 10; those three companies hold 58% of the active fleet. That concentration shows in empty leg availability: only two active legs are typically listed at any time, meaning the 350 is largely a managed-fleet aircraft accessed through Wheels Up memberships and similar programs rather than open charter.
Charter rates run $2,000 to $2,964 per hour depending on variant and operator. Used King Air 350s sell for $2 million to $2.5 million for 1999–2001 vintage and $4 million to $4.5 million for 2009–2011 examples. New King Air 350i aircraft list around $8 million.
Specs at a glance
Interior & cabin
| Passengers | 9 |
| Cabin length | 19.2 ft |
| Cabin width | 4.5 ft |
| Cabin height | 4.8 ft |
| Baggage volume | 71 cu ft |
| Lavatory | Belted, curtained |

| Wi-Fi | Available on most aircraft |
| Cabin floor | Drop aisle |
At 4.8 ft of cabin height, the King Air 350 is a sit-down jet. Expect to duck moving between seats. The lavatory is belted with a curtain — not a full door. Connectivity varies by tail — most operators in this fleet have at least one Wi-Fi-equipped aircraft, but confirm before booking if you need to work in the air.
Operator floor plans vary. Some King Air 350 cabins are configured with a divan that drops the headcount by one or two seats; confirm the layout with the operator before booking.
Range & performance
| Range | 1,806 nm |
| Max cruise | 312 ktas |
| Typical cruise | ~265 ktas |
| Service ceiling | 35,000 ft |
1,806 nm covers most US domestic missions. Coast-to-coast with one stop, transcontinental city pairs east of the Rockies non-stop.
Distances are real great-circle nautical miles from the selected hub. Angular positions are spaced for readability, not actual bearings. Range envelope assumes no wind and a full passenger load.
Charter cost per hour
Charter the King Air 350 at roughly $2,000–$2,500 per flight hour, depending on how far ahead you book. Turboprop jets like this carry 6–9 passengers; the per-seat math improves sharply as you fill the cabin.
Rates are flight-hour pricing. Total cost depends on round-trip vs. one-way, positioning, fuel surcharges, and taxes (~15% on top of base). Run the math on your trip →
History
Beechcraft launched the 350 series as the Super King Air 300 in 1984, then upgraded and renamed it the Super King Air 350 with FAA certification in February 1990. Deliveries began that year. The 350 shares the King Air 200 fuselage cross-section but features a stretched cabin, winglets, and paired PT6A-60A engines rated at 1,050 shp each.
Beechcraft introduced the King Air 350i in 2009 with cabin refinements including contoured seating, improved lighting, and updated avionics. The 350ER (extended range) variant added auxiliary fuel tanks for longer overwater and remote area operations. The 350C version included a large rear cargo door for combined passenger-freight missions. Production continues under Textron Aviation.
Ideal For
- Seven to nine passengers on medium-range routes: Los Angeles to San Francisco (310nm), Dallas to Denver (660nm), or New York to Chicago (720nm)
- Managed-fleet programs where consistent cabin standards and guaranteed availability matter more than open-market charter pricing
- Routes requiring pressurized twin-engine turboprop performance where single-engine alternatives are not acceptable to operator or insurer
- Trips of 2–4 hours where the 1,806nm range and 312-knot cruise suit domestic business travel without jet operating costs
- Wheels Up members and similar fleet programs; more than half the US charter fleet operates within managed program structures
- Cross-country segments where the King Air 350's speed advantage over the King Air 200 (312 vs 289 ktas) saves 15–20 minutes per hour flown

Frequently Asked Questions
How much does it cost to charter a King Air 350?
Charter rates run $2,000 to $2,964 per hour. A 2.5-hour flight from Dallas to Denver typically totals $6,000 to $9,000 before taxes and positioning fees.
How does the King Air 350 compare to the PC-12 NGX?
The King Air 350 is twin-engine with a higher cruise speed (312 vs 290 ktas) and marginally longer range (1,806 vs 1,803nm). Both carry nine passengers in pressurized turboprop cabins. The PC-12 NGX has a wider cabin (5.0ft vs 4.5ft) and larger single rear cargo door. The King Air 350's twin-engine configuration satisfies operators and insurers who require two-engine redundancy for extended overwater or remote routes.
How does the King Air 350 compare to the King Air 200?
The 350 is faster (312 vs 289 ktas), carries more range (1,806 vs 1,580nm), and seats nine versus seven. The cabin is longer (19.2ft vs 16.7ft) but the same width (4.5ft). Both have a belted lavatory. The 350 lists for roughly twice the price of a comparable-year 200 on the used market, but the performance difference justifies the premium on longer routes.
Why are King Air 350 empty legs rare?
Wheels Up Private Jets manages 31 of the 93 US Part 135 aircraft, and West Coast Aviation Services manages 13 more. Aircraft in managed fleet programs typically fly on scheduled member itineraries rather than open empty leg markets. Charter customers who want a King Air 350 usually access it through a managed program membership rather than a spot charter.
What is the difference between the King Air 350 and King Air 350i?
The 350i, introduced in 2009, updated the cabin with contoured seating, improved lighting, and refreshed avionics. Performance figures are essentially unchanged. The 350ER adds auxiliary fuel tanks for extended range. For charter purposes, passengers typically experience the 350i as a noticeably improved interior versus earlier 350 models; the flight performance is the same.
