The United Quest℠ Card is the better choice for frequent United Airlines travelers due to its higher rewards on United purchases and valuable travel benefits. It offers 3X miles on United purchases and a $125 United credit, offsetting its $250 annual fee.
The AAdvantage® Aviator® Red World Elite Mastercard® is still worth considering for American Airlines loyalists, with a lower $99 annual fee and perks like priority boarding and a free checked bag.
