Here's the latest thread.
I am just in converstaion with Avios right now, trying to book tickets, but I have left it too late for some of my options.
You can use your BA points, but what we had to do was transfer them to our normal Avios acct. We had a household acct and my hubby had a BA acct, so they had to split the household acct, transfer the points and then merge the acct again. Don't ask! Anyway it happened very smoothly and within 24 hours we had all the points we needed and I'm about to spend them. Just waiting for them to call me now!
Clubcard vouchers need to be transferred before the end of March to get the bonus 400 miles, but well worth doing if you have any.
