Today (Saturday) was my day to call Citibank and get the info about what of the new benefits I would have on my old Citibank AA cards. The answer was 'all of the new benefits'.
Some are redundant to benefits I already have as an AA LT Gold, but the miles rebates, discounts for onboard purchases and the meager $100 for a $30,000 a year spend are new.
I predict that it is going to get very crowded at boarding time.
