I just got this message:

" Dear LowFlyOver,
As you may know, on November 16, 2011, your
BA Miles will automatically become new Avios points.
If you have 1,000 BA Miles today, you will have 1,000 Avios points. Yet, this is more than just a name change. Avios will be easier to spend and, as of next year, easier to earn.
To start off with a healthy Avios balance, register for the MultiTrip Multiplier offer then book and complete qualifying, full-fare, transatlantic round-trip travel now through December 31, 2011. Fly in any cabin and earn 25,000 bonus Avios for your first trip, 35,000 for your second, and 45,000 for your third and every trip after that.
As an Executive Club member, you can register now
for thousands of bonus Avios and be on your way to reward travel to London and beyond.
Warm regards,

Signature.
Mark Webb
Senior Vice President
