Its based on your billing address and since Euro CC do not use address in the billing. There is no challenge.
Works for me 100% of the time. ;-)
Good Luck
Why do you need to change your address in your AA account?
You can input your (fake?

) US address for CC at the payment.
AA.com allows to use non-registered CC for buying ticket on AA.com.
My registered address on AA.com is non-US.
But I always use my credit cards issued in US on AA.com(and by phone with AA US agents) without any issues.
I believe registered address in AAdvantage account needs not to be same as the address of credit cards for payments.
