Once you've got a price quote, it's worth the effort to call around and get three or four other quotes. Prices vary widely, and one of the most important things to know is that you will often be paying for the plane to get to you, also known as the repositioning fee. Additional charges, common to a lot of flights, include airport charges. At New Jersey's Teterboro, it's $100, while some airports with higher density have an added fee. There are also takeoff fees to consider.
Like scheduled airline service, private jets also have weight limits with regard to the amount of luggage that can be stowed during a trip. Items such as skis and golf clubs are allowed as long as they conform to the dimensions and weight limits of the aircraft. These weight limits vary by aircraft type. Ask your charter sales representative if you have concerns about excess baggage or special items to be included in your luggage.
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.
