Plus, Vista Jet already operates the Lear 60XR among other aircraft (good variety of fleet types for flexibility). Who cares if you now offer a stew and a fancy coffee in an inflexible jet...
I personally think Jet Bird (with the Phenom 100) has a better chance of growing in a depressed market. A cheaper and more flexible aircraft (in this case charter for Jet Bird) will always win out in difficult economic times. More people can afford cheaper aircraft than expensive aircraft.
