Citibank has a card-linked rebate program that’s like Amex Offers, but to date it’s only been available on a limited number of their cards. That’s changed. All of a sudden you’ll find it, for instance, on American Airlines cards and Citi Premier.
This is especially useful because Citi issues a number of Mastercards, which are eligible to be used with SimplyMiles, the American Airlines-Mastercard card-linked offers that award both AAdvantage miles and credit towards elite status.
