As I posted about last month, British Midland Diamond Club miles were supposed to be transferable to British Airways Avios points as of July 3. It appears as if they’ve made the online tool available earlier, as I just completed a mileage transfer from British Midland to British Airways.
To complete a points transfer simply log into your British Airways Executive Club account, click on “Manage my account,” and then click on “Combine my Avios.”

Or if you’re lazy like me you can simply follow this link. 😉

The next page will give you the option of transferring Diamond Club miles to Avios. It’s worth noting that as of now you can only transfer miles one-way, from British Midland to British Airways.

Once you enter the account information and number of miles to transfer, you’ll be asked to confirm the details. Once you’re finished the points will appear in your British Airways account instantly.
There are two interesting things worth noting:
- Your account details have to match exactly. When I first tried to make the transfer I got an error message saying that my account details didn’t match. I went into my British Midland account and made sure everything was formatted the same as in my British Airways account, and that solved the problem.
- If you have a British Midland family account, you can transfer British Midland miles to someone else’s British Airways account. This is a very nice feature. If you have a British Midland family account, just log-in to the account management page, and you’ll see an option to transfer miles to someone else in your family account. This is beneficial because it means you can actually transfer British Midland miles to someone else’s British Airways account. Since I’m a Gold member with British Airways, I’m having everyone in my family account transfer their points to me, since I don’t have to pay for changes or phone ticketing fees.
Meanwhile it can make sense to keep miles in your British Midland account if you plan on booking travel on one of their partners, like Qatar Airways, Virgin Atlantic, etc. More on that here.
