Some other examples of prices come from Avinode, which powers a charter marketplace for brokers and operators and gathers a large amount of data on pricing. Their recent data shows the average price per hour for return trips, for various aircraft. As noted above, these rates can vary depending on when you fly, where you fly and if your flight is one way or return, plus landing fees, ramp fees and any repositioning can all add to the costs. Always ask for a fully inclusive quote from your broker or operator.
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.
