The United Quest℠ Card and the Citi® / AAdvantage® Executive World Elite Mastercard® are both excellent choices for frequent flyers, offering substantial airline-specific perks. The AA Executive World Elite Card is the better option for American Airlines loyalists due to its Admirals Club® membership and 4X miles on AA purchases.
However, the United Quest Card remains a strong contender with its high rewards on United purchases and a $125 annual United credit, making it a valuable choice for United Airlines travelers.
MoneyGeek's card comparison breaks down the card details, rewards and perks to help you decide which is right for you.
