I'm confused. I was so happy to see we can now use AA miles to upgrade on BA. I used 15K AA miles to upgrade my Y class economy to economy plus (I think its called world plus) on a BA flight from Bangalore to LHR. I was actually going to Paris. My BA miles posted on my AADV account from LHR to CDG, but not Bangalore to LHR. Did I actually forfeit 7800 miles plus bonus miles because I upgraded? That doesn't seem fair. I can understand not getting miles on an award ticket, but I paid alot of money for this ticket (well, my company did).
