The Citi® / AAdvantage® Platinum Select® World Elite Mastercard® and the AAdvantage® Aviator® Red World Elite Mastercard® are both excellent choices for American Airlines travelers, offering similar perks like free checked bags and priority boarding. However, the Aviator Red World Elite is the better option due to its generous sign-up bonus and travel insurance.
While the Citi AA Platinum Select offers higher rewards on American Airlines purchases, the Aviator Red World Elite's lower credit score requirement and additional travel protections make it more appealing.
