I know this is sorta a newbie question and may have been sort of answered elsewhere but I have a flight this week that an employer booked for me through AA on AA. I thinks it's an "O" booking code. I have no status with AA but Silver with US. I'm also registered for the current 50% bonus miles promo with both programs. So I assume AA can't see my US status and can't see the promo unless I somehow tie my US DM number to those flights. How can I do this? I assume I might be able to at the ticket counter but I'd like to try to do it before I get to the airport if possible.
