In a wet lease arrangement, the financing entity, or lessor, provides the aircraft, and complete crew, maintenance and insurance (ACMI) to another party at a cost based on hours of operation over a set time period. The lessee pays for fuel, airport fees, duties, taxes and other operational costs. Wet leases generally are established for one to 24 months. (Any shorter period would be considered simply ad hoc charter, which can be thought of as wet lease by the hour or mission.) In the commercial airline world, wet leases are typically utilized to provide supplemental lift during peak traffic seasons or during annual heavy maintenance checks. In the United Kingdom, a wet lease is employed whenever an aircraft is operated under the air operator's certificate (AOC) of the lessor.
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。
As Rachel Raymond from West Orange, N.J., tells it, the day last August when she flew on a private jet ranks as one of the most unreal experiences of her life. Ms. Raymond, and her husband, Daniel, along with their three children, took a flight in a seven-seat jet, a Cessna Citation III, complete with two pilots and a well-stocked bar, from Westchester County Airport, in White Plains, N.Y., to upstate Saratoga Springs. The Raymonds had decided to take an impromptu trip to Lake George because they had found a last-minute deal where they could fly on that route for only $500.
