Got Amex Platinum? Get 1,000 Membership Rewards points for adding a supplementary card

UPDATE – JULY 2025:  This is an old article, and the credit card information given is likely to be out of date.

Last July, I wrote about a special American Express promotion offering 1,000 Membership Rewards points (= 1,000 Avios, amongst other things) for each new supplementary cardholder added to your Platinum charge card account.

Reader Trevor emailed me over the weekend to say that the promotion is still working OK.  He recently added a new supplementary cardholder to his account, and received the 1,000 points 40 days later.  (This sounds like a long time, but the application page says it could take 90 days.)

Full details of this promotion and the application link can be found here.

Each Platinum cardholder can add up to five supplementary cardholders for free, which would get you 5,000 Membership Rewards points.  One of these will receive a Platinum card and will be eligible for their own Priority Pass, can access Eurostar lounges and can claim their own Club Carlson Gold card and other hotel status cards.

The other four supplementary cards will be Gold cards.  These four cards still benefit from the Platinum travel insurance but do not receive any of the other benefits.  (It is possible to make these additional cards into Platinum, but there is a £170 charge.  This is not worth the money in my view.)

Because these are charge cards and not credit cards, Amex undertakes stricter checks when issuing supplementary cards than is usual, so don’t bother trying to get a supplementary card for your dog.

I couldn’t even get one for our nanny 18 months ago, as she wasn’t on the electoral register – Amex insisted on receiving copies of her passport and other documents which was simply too much trouble.
