As I gain my miles with transatlantic YBM flights, my qualificaitn will not be worse, or even better.
I will get less e-upgrades, but will be able to use them eventually, as I purchase U tickets within US.
I do not see really what would be the need for me to become platinum now, except for the lounges.
So, for me, these modifications are in the good direction.
I just wonder if we can change at any moment our preference for 4-500 miles upgrade or 5000 miles. It is not said yet.
