An affinity charter is slightly different in that, although all of the passengers are affiliated with a specific business, group or organization, each pays his own air fare. The passengers might sports or music fans traveling to a special event, or a bunch of friends going on vacation. With this type of charter, none of the seats can be sold to members of public.
Aircraft leases are often used by private aircraft operators, as leases provide the same level of access to an aircraft that ownership provides, without the capital expenditure buying a business jet requires. Leases are offered in two main forms: wet leasing, normally used for short-term access; and dry leasing, typically used for longer term leases. Under wet leases, flight crews are provided in tandem with the aircraft, while operators of dry leased aircraft supply their own crews. Combination wet-dry leases may also be offered, as when an aircraft is wet leased to establish service, and once an in-house flight crew is trained, switched to a dry lease.
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).
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.
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.
