American Express emailed me last week to offer 1,000 Membership Rewards points (= 1,000 Avios, amongst other things) for each new supplementary cardholder added to my Platinum charge card account.

Full details and the application link can be found here.

It is not clear if this is a new offer or a continuation of the one they were promoting earlier in the year.  Either way, there is no deadline stated for applying.

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.  This is not worth the money.)

Remember that the more supplementary cards you have, the more times you will be able to take advantage of any new generous Amex / Foursquare promotions that come along!

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!

Bonus points will added within 30 days of the new card being approved.
