The 'one year's credit for jet fuel' alone is enough to show you how little he knows.
Fuel companies employ massively sensitive credit rating. They give you nothing for free. Ever. And if you don't pay on the nail - the taps get turned off incredibly quickly. There is no way they'd take a risk like this.
Also - I would suggest this post is designed to mislead - is there any way of reading this other than "look at my airliner"?
