The Citi® / AAdvantage® Executive World Elite Mastercard® and the Citi® / AAdvantage® Platinum Select® World Elite Mastercard® are both excellent choices for American Airlines travelers. The AA Executive World Elite is the better option for frequent flyers seeking premium perks like Admirals Club membership and higher 4X miles rewards on AA purchases.
However, the Citi AA Platinum Select is a good contender for those who prefer a lower annual fee and valuable travel perks like free checked bags and priority boarding.
