No chart online, but you can log in, go to Award Manager on the top menu, then go to GlobalAwards on the menu on left, and you get a pop-up window entitled Global Award Table. If you put in the cities you intend to travel between, and search, it will tell you how many miles are needed for such an award in the various classes.
I too think that the new information means that no more than 50% of the miles for any of the particular Superawards can come from bonus miles.
