You will already know that there are many ways to earn Avios, directly with BA, Iberia and Avios (formely Airmiles) or with credit and charge cards such as The Platinum Card, The Gold Card or the BA Premium Plus Credit Card.
However, you can also earn points via other credit cards, and then convert those into Avios.
The Starwood Preferred Guest (SPG) Credit Card
The SPG Credit Card is one such mechanism to do this. If you apply and are accepted for this card, and spend £10,000 within the first 3 months, you are given 10,000 SPG bonus points, alongside the standard SPG points you get for spending on the card (£1 for every full £1 spent).
SPG points can then be converted online to Avios, on a 1:1 basis – so, you get 10,000 Avios.
Additionally, if you get your SPG points balance to 20,000 and transfer those to BA, you get 5,000 bonus Avios, making it 25,000 in total. A nice little earner.
You can also convert SPG points to many other airlines. The card comes with a £75 annual fee.
