Looks more like US will soon be (new)AA

As to your issue, Customer Relations should have forwarded your request to Dividend Miles Service Center, which handles such issues and even has a Subject Line drop-down menu for name/address changes in the linked online form.

I wouldn't argue semantics with them. It's an "error" to you but a "name change" to them ... just say something like, "There's an error with my husband's name. Here's the docs. Could you please change it to his passport name?"

Best wishes.
