I'm a dedicated fan of OZ and Asiana Club, and use OZ every chance I get. When flying domestic flights in the USA I've always tried to book *A flights when possible, meaning US back when they were in *A, or UA. It was great because almost all economy fares earned 100% miles. Now as of the most recent update to OZ's earnings chart, the only UA economy booking classes that still earn 100% miles are Y, B, M, E, U, H. That wipes out all the usual cheaper tickets that I almost always bought from earning 100% miles. It is my understanding that this is all due to UA's actions. Well, I guess UA has just lost me as a customer as a result of this. Not that I was ever a great customer, but I did use them whenever I had a chance. Now I'll either just go with the cheapest ticket, or maybe AA/US and earn miles on my BA account. Not that I need them, but I've got a huge chunk of BA miles and need to have some activity every once in a while to keep my miles from expiring. Seems to me that more and more the airline alliances are crumbling due to the greed/cost cutting of certain airlines. In my mind it's being penny-wise and pound-foolish. I will continue to be loyal to OZ and *A carriers that I feel are "playing fairly" within the alliance, but for those who aren't, forget any loyalty on my part.
