American Keeps the Card Category It Has Never Lost

Best Loyalty Credit Card — Americas · Citibank / American AAdvantage

Best Affinity Card for a frequent flyer program goes to American AAdvantage.

American has the largest cardholder base of any program, and Citibank does a tremendous job promoting the card — limited-time offers to attract new cardholders, often with a free companion ticket on American for signing up.

American, like Marriott, has now won this award every year it has been given.
