works with any amex as long as the numbers are diffrent. A word of caution, amex branded cards as opposed to issued cards i.e. Citi, macys, and similar is supposed to work. If it dosent it will be a little tricky to get the credit. By doing a 3X3BM you can maximize with icing, but remember you need to get approved for all cards, and get them in time. Its cutting a bit close if you will need a recon.
