This is my opinion, do not do this. NetJets is not a stepping stone job. As a new hire you will not get a type rating that will unlock an awesome large cabin gig. You will be in the phenom, latitude, Sovereign, XL, or X. The earliest you will be able to change airplanes is 39 months and the best case scenario is a CL350. As I said, this is not a stepping stone job.
