Not sure if this is the right thread to ask this, but I tried searching (here and the greater internet) and couldn't find a clear answer. I a a diamond in SAN and want to fly TIJ-MEX-CUN on AM (booking through AM). I created an AM account, but can't find anywhere to put my SkyMiles number. Called AM and they were no help. I don't think the agent understood what I was asking. How do I get these accounts to talk to each other so I can get my miles and upgrade benefits? Thank you!
