Via Reddit, by way of Million Mile Secrets, there are unconfirmed reports that American Express is now permitting cardholders to carry five American Express credit cards. This is up from the previous max of four cards. Note, the limit does not apply to the company's charge cards. The distinction is that credit cards allow you to carry a balance while charge cards must be paid in full each month. From the Reddit post:
This is great news for me! I already have four Amex personal credit cards. The Amex Everyday Preferred Credit Card is my main card so I won’t be getting rid of that. I also have the Platinum Delta SkyMiles Credit Card that dates to before I got serious about points and miles. Living in Atlanta, Delta is my main airline and the free checked bag, early boarding, etc. benefits make it worth keeping the card. I have the Starwood Preferred Guest Credit Card that I may eventually cancel as I am not sure I will stick with Starwood post-merger. I will wait and see, but while I have already deemphasized accumulating Starpoints, I don’t want to cut the cord on this card just yet. That leaves the Hilton HHonors Card. I don’t use this card but I just acquired it earlier this year for the signup bonus, so I want to wait until I have held it nearly a year before I cancel.
I have been considering getting a Gold Delta SkyMiles Credit Card card to top off my SkyMiles account. Right now, American Express is offering 50,000 SkyMiles after spending $2,000 during the first three months of card membership. In addition, you can receive a $50 statement credit with this offer. This enhanced signup bonus runs through July 6, so having the ability to get a fifth card would allow me to do this now rather than wait for the next time 50,000 mile promotion! If I decide to apply, I will post whether I was able to be approved for a fifth credit card.
