I just signed up my aadvantage citi card for this and also added my amex optima plat and BofA plat on it too. So if my understanding is correct as long as I use one of my cards that are registered to this account I will get AA miles even if I don't use my AAdvantage citibank card? Also, since everytime you get a replacement amex when it expires (new last 5 digits of account) do you have to change it on idine every time you get a replacement card? Thanks in advance
AMEX "LAST" 5 MUST BE CHANGED (WITH IDINE) IF YOU GET A NEW CARD... You can do that ON-LINE...just sign on to your account... All cards assigned to that IDINE account will earn miles...
