If my calculations are correct, that thing will run about $70,000 PER FILLUP. That's at US airline fuel rates, so probably more internationally and still more at bizjet rates. That's just the gas.
I understand the airplane was just purchased by a "leasing company". I hope they didn't buy it just to strip and scrap, but the fact that even the Qatari royals didn't want to run it anymore is not a good sign.
