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.
Private charter flights offer a range of advantages for busy professionals, including time-efficiency. From quicker check-ins to faster transit times, private jet hire is the perfect way to fulfil multiple meetings in different cities, carry out several site visits in one day or simply have more of an opportunity to remain productive while travelling.
Convenience - There are over 5,000 airports in the US that private planes can use (vs 500 airports for larger commercial aircraft). This means you can often land closer to your true destination.

Private planes also mean that you can travel with your special belongings such as instruments, sports gear, product samples or bring your pet in the cabin.
Though the early Lockheed Jetstar had four, most production business jets have two jet engines, mostly rear-mounted podded engine. If mounted below their low wing, it wouldn't allow sufficient engine clearance without a too long landing gear. The HondaJet is the exception with its over the wing engine pods. Dassault Falcon still builds three-engine models derived from the Falcon 50, and the very light jet market has seen several single-engine design concepts and the introduction of the Cirrus Vision SF50 in 2016.
