Theoretically you can. Customer services told me that there's no reason why not, and the link appears on the "Exec Club" front page when you log onto the website. I live between the Netherlands and London, and use the e-store a lot. My BAEC account is registered in Holland.

I used it successfully for many months, and it's a great way to earn miles.

However they've been having some problems with it, and my transactions since September have been declined. It's run by an external company. They're aware of the problems, and say that they'll be fixed soon and miles should be re-credited.

It's certainly worth a go!
