Several American Airlines co-branded credit cards issued by Citi and Barclays offer priority boarding as a primary travel benefit. The Citi® / AAdvantage® Executive World Elite Mastercard® provides Group 4 boarding, which is the first group of the "General Boarding" process, ensuring you find overhead bin space before the plane gets crowded. For those looking for a more mid-tier option, the Citi® / AAdvantage® Platinum Select® World Elite Mastercard® and the Barclays AAdvantage® Aviator® Red World Elite Mastercard® both offer Group 5 boarding for the primary cardholder and up to four companions traveling on the same reservation. Business owners can also access this perk through the Citi® / AAdvantage® Business™ World Elite Mastercard® or the Barclays AAdvantage® Aviator® World Elite Business Mastercard®. It is important to note that this benefit typically only applies to domestic flights operated by American Airlines and American Eagle. You do not actually need to pay for the flight with the card to receive the perk; the card just needs to be linked to your AAdvantage profile at the time of booking.
