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。
The key words here are prop planes, turboplanes, and light jets. Prop planes like the Cessna Caravan are popular because they're roomy (the seats are like business class, and often configured face to face). More popular these days are planes like the six- to eight-seater Pilatus PC-12, and KingAirs, which fly faster and feel more like jets. And then you get into light jets like Learjets, Embraer Phenom 300s, and Citation CJ3s, and Hawkers, all of which are sleeker and more streamlined, and can fly for four to five hours, for slightly longer trips.
There are some significant additional caveats to discount private plane travel. Often these deals are only for one-way flights, so they will then need to find an alternative way back. It’s also important to understand that there may be extra fees added to the cost of your flight — such as airport or landing fees — so read the contract to determine what’s included and what’s not. De-icing fees, for example, can be significant and may be passed on to consumers, says Jeff Trance, the SVP of private jets for the U.S. for jet charter company Air Partner.
