BA Amex: Earn Up to 10,000 Avios for a Supplementary Card

American Express is offering up to 10,000 Avios for adding your first supplementary card to a British Airways Amex - 10,000 on the British Airways American Express Premium Plus Card, or 5,000 on the free British Airways American Express Credit Card. There is no spend target to hit, and the first supplementary card is free, so it is one of the easiest Avios bonuses going. The offer runs until 12 January 2027.

Amex has brought back a special offer for holders of either BA card who do not currently have a supplementary cardholder on the account. Add one person, and you earn bonus Avios without needing to spend anything on their card.

The only small print is that the bonus Avios will appear in at least two instalments. In practice, reader experience is that they usually post together, just under two separate lines on your statement.

The maths is simple. At a conservative valuation of 1p per Avios, 10,000 Avios is roughly £100 of flight value, and 5,000 Avios is roughly £50. For a free card with no spend requirement, that is a strong return for a couple of minutes of effort.

It looks even better next to the main card's own sign-up reward. You only receive 5,000 Avios for taking out the free BA card as a main cardholder, so the supplementary bonus on that card matches the headline welcome offer. Use our Avios Value Calculator to see what your own redemption might be worth.

You need to hold the British Airways American Express Premium Plus Card or the free British Airways American Express Credit Card, with no supplementary cardholder currently on the account. Then follow these steps:

If you want to check where you stand on other Amex offers first, our Amex welcome bonus eligibility tool is a good starting point. Eligible cardholders can apply for the supplementary card through the link below.

The offer is only available on the first supplementary card added to your American Express account. If you already have a supplementary card in issue, adding another one to the same account will not earn the bonus.

There is also a possible delay. If the person you are adding does not have much of a digital footprint, Amex may email asking for a copy of their passport and a bank statement. That can hold up your bonus by around 3-4 days. This was needed recently when an 18-year-old was added to an existing account.

One grey area: in at least one cardholder's experience, you do get the bonus if you had a supplementary card in the past but cancelled it, even if you add back the same person. That is at your own risk, and not something Amex guarantees.

No other card is running a special offer right now, but the standard bonuses are still available when you add your first supplementary card via the correct link:

One warning: for the Marriott and Nectar cards, the application site still mistakenly shows a higher offer. That deal closed on 31 October, as the terms and conditions confirm, so do not count on it.

You get 10,000 Avios on the British Airways American Express Premium Plus Card and 5,000 Avios on the free British Airways American Express Credit Card, for the first supplementary card only.

No. There is no spend target on the supplementary card, and the first supplementary card is free.

The offer runs until 12 January 2027.

The Avios can arrive as soon as the card is approved, which can be immediate, usually posted in two instalments. If Amex requests ID documents, expect an extra 3-4 days.

If you hold a British Airways Amex and have never added a supplementary cardholder, this is easy value: up to 10,000 Avios, roughly £100 at 1p each, for a free card with no spend target. Add your first supplementary card via the correct Amex page before 12 January 2027, and remember it only works once per account.
