Last Chance: 9000 Free Avios for Adding a Supplementary Card on the BA Amex

Good offers often come back around in the miles and points world. However, that doesn’t mean they hang around forever, and this one is now right at the wire.

If you hold the free British Airways American Express Credit Card and have never added a supplementary cardholder before, then this is your final reminder to act before the offer disappears.

The Clock Is Ticking on 9,000 Free Avios

Until tomorrow, 15 January 2026, you can earn 9,000 Avios by adding a supplementary cardholder to your free British Airways American Express Credit Card, provided that you have never had a supplementary card on this account before. Even if you added one years ago and later cancelled it, you won’t qualify.

The first supplementary card is completely free, so there’s genuinely no financial downside. This is one of those offers where you’re being rewarded handsomely for doing almost nothing.

Feels wrong, doesn't it?

To make sure the bonus tracks correctly, you must apply via the official American Express promotional link (click here). Adding a supplementary card through the app may result in the bonus not being awarded.

How the Avios Are Paid

The bonus is credited in two stages:

• 1,000 Avios

• Followed by 8,000 Avios

What Is a Supplementary Card, Anyway?

A supplementary card is an additional American Express card linked to your main account. It’s typically given to a partner or family member, allowing them to spend on the same account while you remain fully in control.

You stay responsible for payments, can set spending limits, and in some cases the supplementary cardholder may enjoy certain card benefits too. It’s a practical household tool, and right now, a very lucrative Avios opportunity.

Why This Offer Is Particularly Good

To put this into perspective, the standard welcome bonus on the free BA Amex is just 5,000 Avios. Here, you’re earning 9,000 Avios with no spending at all, on a card that already costs nothing to hold.

Last Chance!

This really is last orders. To earn the bonus, you must add your first supplementary card using the correct promotional link before 15 January 2026. If you’ve ever had a supplementary card on this account in the past, you won’t be eligible.

It’s one of the simplest Avios wins you can get, but only if you act before the deadline.

Don’t leave those 9,000 free Avios on the table.
