Unlock 9000 Avios With This Easy Trick With a BA Amex

If you’ve got the free British Airways American Express Credit Card sitting in your wallet and haven’t yet added a supplementary cardholder, now’s the perfect time to act.

9,000 Avios when you add your first supplementary card is a super easy way to earn some extra Avios

American Express has launched a limited-time offer that means you can unlock 9000 Avios with your first supplementary card with this offer. The deal runs until 25th August 2025, and there’s no spending requirement, simply add the card and watch the Avios roll in. Result!

What’s the Deal?

From now until the deadline of 25th August 2025, eligible cardholders can earn 9,000 Avios just by adding a supplementary cardholder to their free BA Amex. The key word here is first. This bonus only applies if you’ve never added a supplementary card to your account before.

Even better, your first supplementary card is free, so there’s nothing to pay and no catch when it comes to fees. You will be getting 9,000 Avios without having to spend a penny!

How Are the Avios Paid?

There’s a small technical detail to be aware of: the Avios bonus will land in two instalments, 1,000 Avios followed by 8,000. But either way, it’s a very generous reward for something that takes just a few minutes to complete, and at no cost to you.

To qualify, you must use the dedicated link on the American Express website. Applying through any other page may mean the bonus doesn’t track.

What Even is a Supplementary Card?

An American Express supplementary card is an extra card connected to the main cardholder’s account, which can be given to a close family member or someone trusted. The person using the supplementary card can make purchases, but the main cardholder is ultimately responsible for all payments.

While spending limits may be set, the card generally shares the same account balance and benefits, such as rewards or travel perks, depending on the original card. This setup can help streamline shared spending and, in some cases, support the supplementary cardholder in building their credit history.

Why This Is a Big Deal

Consider this: when you take out the free BA Amex as a new cardholder, you receive a welcome bonus of 5,000 Avios. So being offered 9,000 Avios just for adding a supplementary card, without needing to spend a penny, is an excellent opportunity to boost your balance.

9,000 will help you on your way to flights to Europe easily

It’s also a great way to share your card’s benefits with a partner or family member, while still earning Avios on their spending.

Other Amex Cards Offer Bonuses Too

Although this 9,000 Avios bonus is exclusive to the free BA Amex for now, several other American Express cards also offer ongoing rewards for adding your first supplementary card:

• The Platinum Card – 5,000 Membership Rewards points

• Preferred Rewards Gold Card – 3,000 Membership Rewards points

• Amex Rewards Credit Card – 2,000 Membership Rewards points

• BA Amex Premium Plus – 3,000 Avios

• Marriott Bonvoy Amex – 3,000 Bonvoy points

• Nectar Credit Card – 3,000 Nectar points

• Harrods Amex Card – 1,000 Harrods Rewards points

• Platinum Cashback / Everyday – £5 cashback

These bonuses aren’t part of a special promotion but are still valid when adding your first supplementary card via the correct link.

Unlock 9000 Avios with Supplementary Card Offer Ends 25th August 2025

To take advantage of this deal, make sure to add your first supplementary card before 25th August 2025 and via the specific promotional page on the Amex website. If you’ve already added one in the past, even if it’s no longer active, you won’t be eligible for the bonus.

This is one of the easiest ways to earn a meaningful chunk of Avios with zero effort. If you haven’t yet taken advantage, now’s the time.
