Using a private jet rental to get to a holiday destination ensures the additional benefit of access to private terminals for faster security check-ins, ensuring that more time is spent enjoying the getaway instead of waiting in line. With its ability to access more locations around the world and enhanced potential for personalisation, chartering privately is the perfect way to travel for pleasure.
Operating leases are generally short-term (less than 10 years in duration), making them attractive when aircraft are needed for a start-up venture, or for the tentative expansion of an established carrier. The short duration of an operating lease also protects against aircraft obsolescence, an important consideration in many countries due to changing noise and environmental laws. In some countries where airlines may be deemed less creditworthy (e.g. the former Soviet Union), operating leases may be the only way for an airline to acquire aircraft. Moreover, it provides the flexibility to the airlines so that they can manage fleet size and composition as closely as possible, expanding and contracting to match demand.
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.
