Best Answer: NetJets fractional interests start at $425,625 (price based on 2009 deliveries and subject to change) for a 1/16 interest (the equivalent of 50 hours of annual flying time) in a Hawker 400XP.Prices vary depending on the aircraft type you choose.here are a lot more variables than just signing a contract. Netjets sells shares in airplanes-as little as 1/16 of a share, which entitles you to 50 hours per year (1/8 share is 100 hours/year, 1/4 share is 200 hours/year, etc).
