I hold both an BA PP Amex and an Amex Platinum. My wife has a basic (blue) BA Amex.
There was some discussion a while back whether or not the referrer and card holder bonuses would be paid if I refer my wife for a Gold while she still holds the BA Amex, but the text of the referral only stated that bonuses would not be earned if the invitee had held an Amex charge card the last in six months (which she doesn't and hasn't).
Does anyone have any recent experience of this situation?
