Business airliner can be contracted as bizliner. Airliners converted into business jets are used by sports teams or VIPs with a large entourage or press corps. Such airplanes can face operational restrictions based on runway length or local noise restrictions. They can be the most expensive type of private jet as they provide the greatest space and capabilities.
According to Jahid Fazal-Karim, owner and chairman of the board of Jetcraft, the sweet spot for buying a plane is between three and five years old in terms of value.

He is often referred to as one of the most powerful players in business and private aviation. Jetcraft
US leveraged lease: Used by foreign airlines importing aircraft from the United States. In a US lease, a Foreign Sales Corporation (FSC) purchases and leases the aircraft, and is tax-exempt so long as at least 50% of the aircraft is made in the US, and at least 50% of its flight miles are flown outside the US. Because of the extensive documentation required for these leases, they have only been used for very expensive aircraft being operated entirely outside the US, such as Boeing 747spurchased for domestic routes within Japan.
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.
