I just received my 25,000 bonus last week after complaining to a CR. A supervisor named "Lynn D." replied in email that she had corrected the problem but that the offer was capped at 25,000 miles.
I replied to Lynn D. in email, asking when I should expect the rest of my bonus miles to post since all of my flights should qualify for a bonus under this sign-up offer (all A and Y fares).
I'll post the reply when/if I get one...
