NRFM - Sorry, but I tend to disagree.
While some (perhaps a handful) private jet buyers could care less about operating and acquisition costs there are far more who are highly conscious about choosing the most cost-effective solution. Its not about the cost but about selecting (and being seen to select) the most cost-effective option within the scope of their requirement.
Individuals/organisations with financial muscle don't always throw their money around with careless abandon and many have fiscal managers who work hard to strain the most out of every buck!
I am looking for comments from those who have experience with these types and especially those who have operated both the A319 and the A320 in corporate configuration.
