No, The Platinum Card® from American Express does not offer cash back rewards. Instead, it gives points on every purchase.
However, you could redeem points for a statement credit, but you only get 0.6 cents per point in value versus much more if you transfer points to Amex’s airline and hotel partners.
Another option is to redeem points directly for travel, which is still not an ideal option compared to transferring points. You can redeem Amex Membership rewards at 1 cent per point towards airfare and 0.7 cents per point for cars, hotels, vacations, or cruises.
