The four-engine A340 was launched alongside the twin-engine A330 in June 1987 at the Paris Airshow. It entered service in January 1993 and since then has become known as the flagship of the Airbus line. The first VIP version of the A340 was delivered in 2006 and has since become an in-demand configuration. In 2011, the VIP version of the A340 was rebranded as the ACJ340. Acknowledging the VIP potential of their airliners, Airbus has been actively marketing their aircraft as ideal options for government heads of state, corporate executives, and wealthy private owners. Since the A340’s are also used as standard airliners, many individual units can be seamlessly integrated into private ownership and VIP charter. This process brings along several benefits including ease of service support and the ability to remain inconspicuous at major travel hubs. As a result, lucrative possibilities are opening for private owners who are looking towards units coming off of commercial airline duties due to the fact that brand new units are incredibly expensive and take a significant amount of time to procure.
