As the application for and mailing of Citibank credit cards is not under the purview of AA or the AAdvantage program, we'll move this to the Citi forum for further discussion. (As mentioned in the forum listing, "reward redemption and valuation topics [for Citibank credit cards] are covered in the AAdvantage"; generic discussion about the logistics of owning a co-branded credit card are generally hosted in the Citi forum.)
Thanks. /JY1024, AAdvantage co-moderator
