King Air 350 Seating Capacity: Cabin Layout, Configurations, and Charter Use

The Beechcraft King Air 350 is one of the most chartered turboprops in the world, and the first question most travelers ask is simple: how many seats does it have? The answer depends on the cabin configuration, but the King Air 350's seating capacity in a standard executive layout typically ranges from eight to nine passengers. This article breaks down every layout option, from double-club executive interiors to high-density commuter setups, and explains how seating decisions affect comfort, baggage, and charter cost.

Key Takeaways

• The Beechcraft King Air 350 seats up to nine passengers in its standard executive configuration: eight seats in the main cabin arranged in two opposing club formations, plus an optional belted lavatory seat at the rear.

• High-density commuter or special-mission layouts can push total seating into the low teens (up to 13 in some configurations), but these trade passenger comfort and luggage space for headcount and are uncommon in private charter.

• The cabin measures roughly 19 feet in length, 4.5 feet in width, and nearly 4 feet 9 inches in height, with a cabin volume around 355 cubic feet, making it one of the roomiest turboprops in the King Air series.

• King Air 350's seating capacity can be adapted for business travel, family trips, or medical missions; Jettly can source different cabin layouts depending on route, passenger count, and baggage needs.

Overview of the Beechcraft King Air 350

The Beechcraft King Air 350 is a twin-turboprop aircraft in the broader Beechcraft King Air family. It entered production in 1990, and its history traces to a stretched development of the Super King Air 300 and 200 line, adding roughly three feet of fuselage length over its predecessor. In standard executive configuration, King Air 350 seating capacity is eight to nine passengers, placing it firmly in the upper tier of the turboprop charter category.

Within the King Air series, the 350 sits above the King Air 200 and 250 in cabin size, and it served as the direct predecessor to the King Air 350i and later the King Air 360. The aircraft is powered by two Pratt & Whitney PT6A-60A engines, is equipped with the core avionics and systems expected in this model family, reaches a maximum cruise speed of 312 knots, and has a maximum range of 1,806 nautical miles. Its service ceiling is 35,000 feet, and the cabin volume is roughly 355 cubic feet with about 55 cubic feet of internal pressurized baggage space.

Corporate operators, air ambulance services, military organizations (several air force fleets operate King Air variants for reconnaissance and transport), and charter providers around the world fly the King Air 350. That breadth of use comes down to a balance of runway performance, operating efficiency, and a spacious cabin that accommodates most small-group missions.

Standard King Air 350 Seating Capacity and Layout

In a typical private charter layout, the Beechcraft King Air 350 seats eight passengers in the main cabin, plus a ninth in the belted lavatory. A belt-certified lavatory seat at the rear can be used as an additional passenger position, giving a practical range of eight to nine seats.

Most executive King Air 350 cabins are configured with two sets of double-club seats: four facing four. The seating arrangement often includes fold-out tables between each club for dining or working during flights. Some layouts add a side-facing seat near the entry door or a forward-facing seat aft, but the double-club pattern dominates the charter market.

While the aircraft's type certificate allows configurations up to 17 people (including crew), private charter trips almost always prioritize legroom, workspace, and baggage capacity over maximum headcount. A passenger entering through the main entry door walks past the cockpit partition into the forward club of four seats, then past the fold-out tables into the aft club. Overhead shelving, side ledges, and a refreshment center line the cabin. Compared to light jets or smaller turboprops, the seat pitch feels generous; passengers seated in club formation have enough room to cross their legs.

Children can safely use the same seats as adults with proper restraints, but operators often limit bookings to eight or nine passengers based on weight-and-balance calculations for the specific route and conditions.

Executive vs High-Density Seating Configurations

The King Air 350 and related Super King Air variants support multiple cabin layouts. The gap between "executive" and "commuter" configurations is wide enough to change the entire flying experience.

The typical executive layout used by business travelers and commercial customers features eight leather seats in two opposing clubs, fold-out tables, and a belted lavatory seat. This setup prioritizes comfort and workspace. The aircraft can also be reconfigured for special missions such as air ambulance or cargo transport, and these mission-specific interiors look nothing like a standard charter cabin.

Some operators configure the Beechcraft King Air 350 in a high-density shuttle style, using rows of lightweight forward-facing seats (some weighing as little as 26 pounds each versus 60-80 pounds for an executive seat). One documented 350ER high-density layout installed up to 13 seats, including a belted lavatory and folding chairs. The King Air 350's maximum certified occupancy can reach up to 17 people depending on the configuration, per FAA type certificate data.

Air ambulance configurations may reduce passenger seat count to two to four seated positions, creating space for stretchers, medical equipment, and attendant stations. In these special mission operations, "seating capacity" reflects crew plus limited passengers.

A quick comparison of layout types:

Layout Type	Seating Capacity	Features	Typical Use Cases
Executive	8-9	Double-club seats, fold-out tables, belted lavatory seat	Business travel, family trips
Commuter/High-Density	Up to 13	Forward-facing lightweight seats, reduced luggage space	Shuttle, commuter flights
Air Ambulance	2-4 seated plus stretchers	Medical equipment, attendant stations	Medical transport

Jettly can request specific layouts from its operator partners when travelers need something beyond the standard executive arrangement.

Dimensions, Comfort, and Cabin Experience

More seats do not always mean a better flight. Passenger comfort depends on how those seats relate to the cabin's physical dimensions and the number of people on board.

The cabin dimensions of the Beechcraft King Air 350 are about 19 feet long and 4.5 feet wide, with a height of approximately 4 feet 9 inches. Most adults under six feet tall can walk the aisle without ducking. The King Air 350's cabin is designed for comfort with ergonomic leather seats, and the double-club arrangement means passengers face each other, which is ideal for business discussions or family interaction. Large oval windows, standard across the Super King Air line, let in more natural light than many light jets in the same class.

Standard layouts in the King Air 350 include storage areas and a refreshment center. Later models and refurbished cabins often add power outlets, USB ports, and Wi-Fi availability. Modern soundproofing packages reduce the characteristic turboprop hum, though the cabin will never be as quiet as a jet at altitude.

Flying with fewer than the maximum seats filled makes a noticeable difference. Six passengers in an eight-seat cabin have room to spread out, use the tables freely, and stow bags within arm's reach. Jettly can match passenger count to aircraft size; sometimes a smaller turboprop or a light jet fits a group of four better than a half-empty King Air 350, drawing on access to a broad range of private charter aircraft.

King Air 350i and 360: Seating Compared Within the King Air Series

The King Air 350 evolved into the Beechcraft King Air 350i (improved interior, upgraded avionics) and then the King Air 360 and 360ER, introduced by Textron Aviation in late 2020. Seating capacity across these models remains broadly similar, with incremental comfort and technology upgrades rather than layout changes.

King Air 350i and 360 models generally retain the eight- to nine-passenger executive seating norm. The differences show up in interior materials, LED lighting, improved soundproofing, synthetic vision on the flight deck, and sometimes more flexible seating rails. The cockpit avionics shifted to newer Rockwell Collins Pro Line Fusion displays, but the cabin footprint stayed the same.

Smaller Beechcraft King Air variants tell a different story. The King Air 90 and 100 series typically seat five to seven. The King Air 200/250 handles six to eight. The "super king" 300/350 family is the preferred choice when occupancy is seven to nine travelers, and the route requires range beyond 1,000 nautical miles.

The King Air 360ER can accommodate up to 15 occupants under certain government or special-mission configurations, but those layouts are not standard for business charter and rarely appear on consumer-facing inventory. For charter travelers, the King Air 350 remains the sweet spot in the King Air series for both seating capacity and operating cost on sectors under 1,500 nautical miles.

Weight, Baggage, and Practical Seating Limits

Legal seating capacity is only one constraint. The real passenger limit on any given flight depends on weight-and-balance, baggage volume, fuel load, and runway length at both ends of the route.

The King Air 350 has a useful load of over 5,000 pounds (approximately 5,145 lb in the 360 variant). Maximum takeoff weight sits around 15,000 lb. After accounting for crew, full fuel, and the aircraft's empty weight, the remaining payload for passengers and luggage can drop to roughly 1,500-2,000 lb on longer routes. That math matters: nine adults averaging 200 lb each plus bags can push close to the limit on a 1,400 nm sector.

In practical terms, the King Air 350's internal pressurized baggage compartment holds about 55 cubic feet and up to 550 lb. Wing lockers on some configurations add more external storage. Eight passengers with standard rolling suitcases and carry-ons fit comfortably. Eight passengers with golf bags or ski equipment may require planning; operators sometimes cap the passenger count at seven to stay within weight limits.

Common scenarios:

• 8 adults with light luggage on a 600 nm route: no issue

• 8 adults with golf bags on a 1,200 nm route: likely needs fuel stop or one fewer passenger

• 6 adults with heavy cargo or film equipment: comfortable fit with room to spare

Jettly asks travelers to provide headcount, approximate weights, and baggage details during quoting so operators can confirm safe loading, while also outlining the key factors that drive one private flight’s cost. The pilot in command and operator always have final authority on whether the planned load is acceptable for conditions on the day.

Use Cases: How Different Travelers Use King Air 350 Seating

Groups between four and nine passengers cover most King Air 350 charter bookings, fitting neatly within common private jet passenger capacity ranges for light and midsize aircraft. Here is how different trip types use the cabin.

Corporate shuttle: Six to eight executives flying between regional business centers (Dallas to Houston, Toronto to Ottawa) use the double-club layout for in-flight meetings. The fold-out tables accommodate laptops, documents, and catering. The King Air 350 can land at smaller airports closer to final destinations, saving ground transfer time, and corporate flyers can estimate trip budgets in advance with tools like Jettly's jet card flight cost estimator.

Family or leisure travel: A multi-generation family of up to eight heading to a ski destination or island resort. Children sit across from parents in the club formation, and the baggage compartment handles skis or surfboards with advance planning. Capable of operating from high-altitude airports and short runways, the aircraft reaches destinations that many jets cannot, while savvy travelers apply tips for booking the cheapest private jet flights to keep family trips within budget.

Air ambulance and medical transport: Operators remove or reconfigure seats to accommodate stretchers, ventilators, and medical staff. The King Air 350's large entry door, pressurized cabin, and climb performance make it a workhorse for medical missions around the world, similar to how the King Air 200 charter aircraft is used for versatile corporate and special-mission flying.

Jettly's platform can filter available aircraft, including King Air 350, 350i, and similar Super King Air types, by passenger count, route distance, and prices, and also supports travelers who simply want to buy a seat on a private jet rather than charter the entire aircraft.

King Air 350 vs Light Jets: Seating and Cabin Trade-Offs

The King Air 350 often matches or exceeds the seating capacity of popular light jets while costing less per flight hour and performing better on short runways. The trade-off is speed.

Many light jets (Citation CJ series, Embraer Phenom 300) seat six to eight passengers. The King Air 350's cabin comfortably handles eight to nine. The turboprop cabin is wider at the floor and offers more generous headroom. Light jets typically cruise 50-100 knots faster and operate at higher altitudes with a quieter ride, and platforms like Jettly position themselves as a flexible NetJets alternative for accessing these aircraft on demand.

For flights under 500-700 nautical miles with seven to nine passengers, the time difference between a King Air 350 and a small jet may only be 15-30 minutes gate-to-gate, especially when the turboprop can use a closer airport. Direct operating costs for the King Air 350 run around $1,300 to $1,500 per hour, often lower than comparable light jets on the same sector, which can materially influence the cost of a single private flight.

Jettly's platform allows side-by-side comparison of King Air 350 vs light jet options for the same route, displaying both seating capacity and estimated flight time, and can also help travelers share empty seats on private flights to reduce per-passenger cost.

Buying vs Chartering: When King Air 350 Capacity Matters Most

Some readers may be evaluating whether to purchase a Beechcraft King Air 350 or charter one on demand. Seating capacity is a factor, but the financial math usually decides.

Owners typically select the King Air 350 when they move six to nine passengers between secondary cities with short runways on a near-daily basis and are comfortable with the total private jet ownership costs involved. The aircraft's rugged landing gear and efficient engines support that kind of short-field operation. Hawker Beechcraft (now Textron Aviation) built the aircraft with exactly these operators in mind.

The purchase price and ongoing costs are substantial. Used King Air 350 aircraft continue to sell on the market, with prices ranging from $2.5 million to $3.8 million. King Air 350i costs between $4.1 million and $6.5 million on the current market; in 2019, a new King Air 350i listed at $7.755 million from the factory. Annual operating cost for the King Air 350 is approximately $1,163,166, covering crew, maintenance, insurance, hangar, and other modifications, figures that make guides to affordable planes and budget-friendly aircraft choices particularly relevant for cost-conscious buyers.

For businesses or families that only need eight to nine seats a few times per month, chartering through Jettly offers better financial flexibility than buying and managing a Beechcraft King Air outright, and guides on how much it costs to rent a private jet can help frame that decision.

Frequently Asked Questions

These questions address practical seating details not fully covered above.

How many passengers can the King Air 350 safely carry on a typical charter flight?

Most chartered Beechcraft King Air 350 aircraft are configured for eight passengers in the main cabin plus an optional ninth seat in the belted lavatory. The final allowed count depends on operator configuration, weight-and-balance, and route specifics. Flights from high-altitude airports or on longer sectors may require fewer passengers to stay within performance limits.

Is the belted lavatory seat on a King Air 350 normally used for passengers?

The rear lavatory seat is certified for use during taxi, takeoff, and landing. Many operators reserve it as an occasional seat. Some charter clients prefer to treat the King Air 350 as an eight-seat cabin for comfort, keeping the lavatory area free for its intended purpose throughout the flight.

Can the King Air 350 cabin be reconfigured between flights?

Many Super King Air 350 interiors use modular seating rails that allow removal or repositioning of seats between missions.
