Free BA Amex? Add a Supplementary Card and Pocket 9,000 Avios

If you already hold the free British Airways American Express Credit Card but have never added a supplementary cardholder, you’re sitting on a simple, risk‑free way to bag 9,000 Avios—no extra spending required. Between now and 25 August, just add your first free add‑on card to your Free BA Amex and the points are yours.

Why This Offer Is So Good

• No minimum spend required. Simply add your first supplementary card through this specific Amex page.
• Huge uplift over the standard bonus: you normally get only 5,000 Avios when you sign up as the primary cardholder.
• Instant family benefit: any household member can start earning on everyday groceries, fuel or utility bills—while you pocket the Avios.

Step-by‑Step: How to Claim Your 9,000 Avios

1. Visit this special offer page (you must use the exact link for tracking).
2. Add your first supplementary cardholder—it’s completely free.
3. Sit back: your 9,000‑Avios bonus will post in at least two instalments (1,000 then 8,000) according to the T&Cs

Pro tip: If you haven’t got the FREE BA Amex and eligible for the sign-up bonus by completing the £2,000 in three‑month spend target, this is a great time to do so. Pair your 5,000‑Avios sign‑up bonus with this 9,000‑Avios “add‑on” offer, and you’ll have 14,000 Avios (or 15,000 Avios if you were referred) after just one free card.

What to Watch Out For

• First and only: this bonus applies only to your very first supplementary card. Adding a second or third won’t trigger any extra Avios.
• Strict deadline: everything must be done by 11:59 PM on 25 August UK time.
• Correct application page: if you stray from the special link, the bonus may not track.

Next Steps

1. Check you don’t already have a free supplementary card on your BA Amex.
2. Head to the offer page and add your supplementary card.
3. Watch 1,000 Avios drop into your account, followed by 8,000 shortly after.

This really is a free pile of points—no fee, no spend, no catch. If you’ve never added a supplementary card, there’s no better way to supercharge your Avios balance before the summer holidays wind down.
