I received an email from BA offering me 3000 Avios for adding a Supplementary Cardholder to my BAPP account, however it says for the 1st additional card only but I already have an 1 additional cardholder. Is there a chance I would get the 3000 Avios for the 2nd cardholder? Otherwise I am not sure why they sent it to me? Or is it just because of their crap IT doesn't know I already I have added one already?
