I didn't think this warranted its own thread so I'll put it here.
I just got 2 Citi Hilton cards. When I try adding them to my online profile (which currently contains 2 AA cards) it gives me an error message of
"The account number you've entered can't be linked to this Account Online User ID at this time. Please register this account using a separate User ID. To do this, you'll need to sign off, return to the home page and select Register."
I've been getting this message for 3 days now. Anyone else ever get this and know how to get around it?
