The Centurion: American Express's most exclusive card. Allegedly once used to purchase — on credit, with a credit card — a $54,000,000 plane for a wealthy individual. A card that is by invitation only; made of titanium; "limitless" (based on your spending history); a card that elevates you to first class for free; a card that will put you on the highest level of reward point systems with hundreds of hotels and airlines. A card with a $5,000 set-up fee, and a $2,500 annual fee.
A card that requires you spend over $250,000 in a single year on your AMEX before you're considered for an invite.
I have read a few articles that make this "by invite only" reputation seem not so exclusive, in that you can call and request to be invited if you meet the requirements.
My question is this: should I come up with an American Express Centurion card, it can be assumed that I am spending a significant amount of money. At a minimum, nearly $21,000 per month. If my spending suddenly drops below this level — dramatically — but I continue to pay the annual fee ($2,500), will I keep the Centurion card?
