One particular type of operating lease is the wet lease, in which the aircraft is leased together with its crew. Such leases are generally on a short-term basis to cover bursts in demand, such as the Hajj pilgrimage. Unlike a charter flight, a wet-leased aircraft operates as part of the leasing carrier's fleet and with that carrier's airline code, although it often retains the livery of its owner.
Aircraft brokers make it their goal to become trusted advisors to the buyer. A professional Aircraft Broker will not only present the most current and desirable available aircraft on the market; they will also guide the buyer throughout the entire transaction, including price negotiations, as well as recommendations for legal and tax advisors, aircraft inspection specialists, suitable FBO facilities, and any other services to assist in consummating the best possible deal for the aircraft purchase.
Under American and British accounting rules, a finance lease is generally defined as one in which the lessor receives substantially all rights of ownership, or in which the present value of the minimum lease payments for the duration of the lease exceeds 90% of the fair market value of the aircraft. If a lease is defined as a finance lease, it must be counted as an asset of the company, in contrast to an operating lease which only affects the company's cash flow.
About 70% of the fleet was in North America at the end of 2011. The European market is the next largest, with growing activity in the Middle East, Asia, and Central America.
