I happened to login to my Amex account and see that there is a bonus offer of an additional 40% BA Avios awarded for transfering Amex MR to BA. The normal transfer rate for MR to BA is 1:1, but with this offer it's 1:1.4. This is a transfer that is a sweet deal for those of us that take advantage of the "sweet spot" for flying from the West coast directly to several of the Hawaiin islands on American Airlines but booked through BA using Avios. The cost is only 25,000 points for roundtrip when it normally would cost at least 40,000 if booked directly through American.
I assume this isn't a narrowly targeted offer, so many of you might see it too. I found it by going into my amex acct, then Explore Rewards, then transfer points in the dropdown menu under the Explore Rewards text. Then look for the list of airlines and those with a bonus offer have the word "Offer" in upper left corner of their logo.
hopefully this is helpful to some of you .
