Gulfv,
Don't get confused by the intial reply, what the "friendly" chap from Glasgow possibly meant to say was if you follow the link:
http://www.pprune.org/forums/showthr...hlight=Netjets
you'll find some of your very valid questions, but by no means all of them, answered.
The best thing to do would probably be post your question on the above link and hopefully you'll get some answers - some of which interest me but haven't been answered previously.
Cheers MD
