Long time readers of InsideFlyer know that we’ve always been high on the Citi/AAdvantage MasterCard credit card, and now we’re not alone. MasterCard International recently honored this credit card as an inaugural recipient of the North America Co-Brand Partner of the Year Award. The award also included induction into the newly constituted MasterCard International Co-Brand Hall of Fame. Introduced in 1987, the Citi/AAdvantage Card program was among the first co-branded airline programs and has grown to become one of the largest co-brand programs in the world. Today, there are 9,500 MasterCard co-brand programs available in the United States and Canada.
