HT:  Loyalty Lobby.  He already has charts up on his blog.  The changes mostly affect Star Alliance awards and they will upset the majority of people on FlyerTalk who have been collecting miles for this purpose.  So far the changes seem to affect Europe, Asia, South Africa, the Middle East/Africa and Others.  For eco-travelers, I have recommended collecting LifeMiles to use on intra South/Central American awards and these have not been affected.  See my main post for more about best uses of AviancaTaca Lifemiles.
