I had a brief meeting with my CEO last week. Our company spends 80K - 120K
annually on commercial flights. He knows I am a private pilot and he asked
me if I could prepare a comparative analysis of alternatives such as
fractional ownership, outright ownership, leaseback or charter.

If you're goal is purely to save money on airfare, you WILL not succeed in most
circumstances.

You will need to factor in all the other things like ground connections if you
fly to places without scheduled air service regularly, and the time your employees
spend down due to the inherent time overheads in flying commercially.
