Until tonight (Saturday) American Express has doubled the bonus you get when you add a supplementary card to:
- American Express Preferred Rewards Gold
- the British Airways American Express card
- the British Airways Premium Plus American Express card

Supplementary cards are free, so this is a very easy pile of points worth up to 6,000 Avios or 6,000 Membership Rewards.
IMPORTANT: There is a separate offer, also ending today, for adding a supplementary card to a Marriott Bonvoy, Nectar or American Express Rewards Credit Card. You can learn more about those bonuses in this article.
What bonus can I get for adding a supplementary card?
This offer is only available on the FIRST supplementary card added to your American Express account. If you already have a supplementary card in issue, you will not get the bonus if you add another one to the same account.
You MUST use this page of the American Express website to apply.
This is what you receive:
American Express Preferred Rewards Gold
Receive 3,000 Membership Rewards points when the additional card is approved, plus a further 3,000 if your additional card spends £500 in the first three months
British Airways American Express
Receive 1,000 Avios when the additional card is approved, plus a further 1,000 if your additional card spends £300 in the first three months
British Airways Premium Plus American Express
Receive 3,000 Avios when the additional card is approved, plus a further 3,000 if your additional card spends £500 in the first three months
How long does the offer run?
Not long! The offer ends tonight, Saturday 31st July.
If you have any of the three cards above and have never issued a supplementary card in the past, now is as good a time as you will get.
You must use this special page of the American Express website to add your supplementary card. If you use any other page of the Amex website, your bonus will not track.
