The Citi Chairman Amex Card is for people who live such luxurious lives they don't want to feel limited by spending caps. It's even more exclusive now that Citi stopped offering it, meaning only the people who signed up in time still get to enjoy the perks.

Like other elite credit cards, it comes with a personal concierge service that does everything from planning a child's birthday party to booking tickets to a sold-out Broadway show. Its travel benefits also include many private jet deals -- including a consultant who will help you decide which jet is right for you to purchase based on your flying habits.

American Express Green, Gold, Platinum and Centurion cards don't come with pre-set spending limits either.
