由於商務噴射機的價格昂貴，分數擁有權（Fractional Ownership）是指有意購買商務噴射機的買主，不需購整架商務噴射機。透過如Netjets或是Flex Jet專門進行分數擁有權的商務噴射機公司，買主可以購買1/4、1/8或其它比例的商務機擁有權，而由商務噴射機公司來進行操作-包括飛行及維修。參加分數擁有權計劃的顧客，每個月可有固定時數的飛行。由於操作分數擁有權的商務噴射機公司，擁有許多飛機，因此顧客雖然擁有某架飛機的擁有權，但並不一定搭乘擁有的飛機。因此參加分數擁有權的計劃，顧客是以分擔商務噴射機公司購機和操作成本，以較低廉的價格，來享受商務噴射機飛行服務，但是就因為每個買主只擁有"部分所有權"而且並非天天都需要用到飛機，所以需要飛行得事先預約，再由商務噴射機公司安排飛機和空勤組員。
Finance leasing is attractive to the lessee because the lessee may claim depreciation deductions over the aircraft's useful life, which offset the profits from the lease for tax purposes, and deduct interest paid to those creditors who financed the purchase. This has made aircraft a popular form of tax shelter for investors, and has also made finance leasing a cheaper alternative to operating leases or secured purchasing.
Operating leases are generally short-term (less than 10 years in duration), making them attractive when aircraft are needed for a start-up venture, or for the tentative expansion of an established carrier. The short duration of an operating lease also protects against aircraft obsolescence, an important consideration in many countries due to changing noise and environmental laws. In some countries where airlines may be deemed less creditworthy (e.g. the former Soviet Union), operating leases may be the only way for an airline to acquire aircraft. Moreover, it provides the flexibility to the airlines so that they can manage fleet size and composition as closely as possible, expanding and contracting to match demand.
In addition to luxurious cabin fittings and a host of amenities, many of today's private jets also in-flight connectivity systems allowing passengers to connect to the Internet in much the same manner as they would in their own homes and offices, allowing busy CEOs to conduct important business meetings at 40,000 feet. Whether it's visiting multiple clients or offices in a single day, or carrying your family to a top-level vacation destination, private jets provide an incredibly fast, safe, and secure travel alternative for you, your friends and family, and your employees, all in unmatched style and luxury.
Purchasing an aircraft is a significant investment. As with any major purchase, private aircraft buyers want to be sure they’re seeing all the available private jets for sale that meet their criteria, so that they can compare the price, configuration and condition of all such currently available private jets for sale worldwide. Moreover, many buyers who plunge into the market without the help of an expert advisor may not even have properly identified the best airplane for their needs, and a buyer can’t make a great deal on the wrong airplane.
On 1 April 2017, there were 22,368 business jets in the worldwide fleet, of which 11.2% were for sale. 5-year old aircraft residual value level is at a 56% of the list price. A new business aircraft depreciate by 50% in five years before depreciation flattens between years 10 and 15, and the owner of a 15 to 20 years old is often the last, matching luxury cars.
