Privacy is one of the main advantages of a charter flight.  Unlike a commercial flight, where travelers are herded through a crowded airport, having to undergo an intrusive security screening, passengers on a charter flight depart from a private facility known as an FBO.  At most private airports, passengers can pull their cars right up to the plane.
With a charter flight, you rent the entire aircraft, rather than just one seat. The aircraft can be large or small, and flights can be one-way or round-trip. The charter could be made on a flight-only basis, might include ground services such as transportation to or from meetings or could be part of a complete vacation package. Charter flights offer more flexibility than scheduled flights, with a wider choice of destinations and tailor-made itineraries.
Finance leasing, also known as "capital leasing", is a longer-term arrangement in which the operator comes closer to effectively "owning" the aircraft. It involves a more complicated transaction in which a lessor, often a special purpose company (SPC) or partnership, purchases the aircraft through a combination of debt and equity financing, and then leases it to the operator. The operator may have the option to purchase the aircraft at the expiration of the lease, or may automatically receive the aircraft at the expiration of the lease.

Conversely, the aircraft's residual value at the end of the lease is an important consideration for the owner. The owner may require that the aircraft be returned in the same maintenance condition (e.g. post-C check) as it was delivered, so as to expedite turnaround to the next operator. Like leases in other fields, a security deposit is often required.
In October 2017 Jetcraft forecasts 8,349 unit deliveries in the next decade for $252 billion, a 30.2 $M average. Cessna should lead the numbers with 27.3% of the deliveries ahead of Bombardier with 20.9% while Gulfstream would almost lead the revenue market share with 27.8% trailing Bombardier with 29.2%.[6] For 2016-2025, Jetcraft forecasted Pratt & Whitney Canada should be the first engine supplier with 30% of the $24B revenue, in front of the current leader Rolls-Royce at 25%. Honeywell will hold 45% of the avionics $16B revenue ahead of Rockwell Collins with 37% and Garmin.[10]
