Bill Gates may have the most dough, but he doesn't get FF miles for Gulfstream V hops. Lets see where we all rank on the FlyerTalk 400: reply '5' if less than 100,000 miles; '4' if 100,001 to 500,000; '3' if 500,001 to 1,000,000; '2' if 1,000,001 to 2,000,000; and '1' if 2,000,001 + (total miles available for rewards, all airline programs).
