We would rather say this plainly than have you find out later.
Fractional is the better instrument if you fly a lot — 200 hours a year and
upward — on consistent missions, in a consistent aircraft type, with high predictability,
and you want the aircraft to feel like yours. At that volume the per-hour economics work,
the monthly management fee is spread thin, and the consistency of flying the same type with
the same standard is worth real money.
It also wins on tax treatment for some structures. That is genuinely a question for your
accountant and not for a website, and any charter company that tells you otherwise on a
marketing page is not being careful with you.
The card wins when your flying is somewhere between 25 and 150 hours a
year, when your travel pattern might change, when you would rather your capital stayed
liquid, and when you want to choose the aircraft category by trip rather than fly one type
for everything.
If your situation is the first paragraph, say so on the phone and we will tell you so.
There is no version of this business that is improved by selling someone the wrong product.
