Customers spend time with a full-service design team to decide how they want to outfit the plane’s interior. Interiors can be customized to align with the branding of a company, the tastes of an owner, or the operational needs of the flight department. Some notable interior options for the Citation Longitude are the side-facing couch, optional crew jump seat, and solid surface flooring. The Longitude offers an inflight-accessible baggage compartment, and its ceiling extends to 6 feet, making it easy for most people to stand up. Textron Aviation
Fliers with flexibility should sign up for empty-leg email lists of companies like Magellan Jets, who regularly send out emails selling discounted flights from, say, the plane of a corporate exec who flew to Los Angeles but is looking to offset his cost of getting the plane back to New York. “I wouldn’t say that the cost of flying private has gone down, but there are new ways of pricing charter that makes it more accessible,” says David Zipkin, co-founder and VP of Tradewind, the service known for semi-private flights in the Northeast and Caribbean. “In our case, we save people money with our shared charters, and we also sell discounted empty legs.”
Under American and British accounting rules, a finance lease is generally defined as one in which the lessor receives substantially all rights of ownership, or in which the present value of the minimum lease payments for the duration of the lease exceeds 90% of the fair market value of the aircraft. If a lease is defined as a finance lease, it must be counted as an asset of the company, in contrast to an operating lease which only affects the company's cash flow.
In the United States, business aircraft may be operated under either FAR 91 as private operations for the business purposes of the owner, or under FAR 135 as commercial operations for the business purposes of a third party. One common arrangement for operational flexibility purposes is for the aircraft's owner to operate the aircraft under FAR 91 when needed for its own purposes, and to allow a third-party charter-manager to operate it under FAR 135 when the aircraft is needed for the business purposes of third parties (such as for other entities within the corporate group of the aircraft's owner).[16]

A single-entity charter is one in which an individual or company charters a plane and bears the entire cost of the flight, so that the passengers do not pay their own airfare. There is no minimum passenger requirement, since the cost is per flight, not per person. Single-entity charters are typically used for business purposes -- for example, travel to meetings and conferences, incentive travel or VIP leisure travel.

Though the early Lockheed Jetstar had four, most production business jets have two jet engines, mostly rear-mounted podded engine. If mounted below their low wing, it wouldn't allow sufficient engine clearance without a too long landing gear. The HondaJet is the exception with its over the wing engine pods. Dassault Falcon still builds three-engine models derived from the Falcon 50, and the very light jet market has seen several single-engine design concepts and the introduction of the Cirrus Vision SF50 in 2016.
