American Express has launched a bonus promotion worth 1,000 Membership Rewards points (= 1,000 Avios, amongst other things) for each new supplementary cardholder you add to your Platinum charge card account.
Full details and the application link can be found here.
Each Platinum cardholder can add up to five supplementary cardholders for free. 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. A Platinum supplementary cardholders cannot have their own Cathay Pacific Marco Polo Gold card, however.
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 £175 charge.)
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 last year, 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.
Even if you are planning to cancel your Platinum card in the near future, there is no reason why you shouldn’t get it on this deal and earn some extra Membership Rewards points whilst you can.
