As of this evening, AA.com still shows that the top mileage bonus Citibank AAdvantage card is the Platinum Select card, offering 15,000 bonus miles after first purchase, one free companion voucher (with strings) and no fee for the first year.
I have been all over AA.com and the Citicard website, but no mention of a 25,000 bonus mile offer. I also was in DFW yesterday and all the cards they were hawking were the standard 15,000 (Platinum Select) and 12,500 bonus mile cards.
Any link, other than the phone number? An offer code to ask for?
