Launched back in 1984, the American Express Platinum card, which comes without a pre-set spending limit and with a $450 annual fee, has been setting the standard for elite cards for decades.

A platinum personal concierge assists card members with everything from gift buying and reservations to travel services. Platinum card members enjoy premium access to exclusive concerts and special events and to airport lounges of select airlines when traveling.

And if card members should encounter any problems or concerns when traveling, a 24-hour, global assistance hotline staff is available to help.

The card's extensive travel benefits include limousine and private yacht programs and a platinum villas program good for stays at Four Seasons Residence Clubs, LaCURE and Villas of Distinction. The Mansion at MGM Grand is available to card members, but it must be confirmed 60 days prior to arrival.

The American Express Platinum card also comes with a rewards program. You earn one rewards point for every dollar that you spend on the card, double rewards points at American Express Travel and bonus rewards points when you shop online at more than 200 retailers through BonusPointsMall.com.

There is no limit and no expiration date on points earned with the card. Points may be redeemed for everything from fashion and jewelry and watches to sports cars, airfares and special rooms and amenities at more than 600 luxury hotel properties worldwide as well as luxury lifestyle goods.
