The United Quest℠ Card and United Club℠ Infinite Card are both excellent choices for frequent United Airlines flyers, offering substantial rewards and travel perks. The United Quest is the better option for most travelers due to its lower annual fee and valuable travel credits, making it more accessible and cost-effective. It offers high rewards on United purchases, travel and dining, along with a substantial sign-up bonus.
However, the United Club Infinite should be considered for those who prioritize unlimited lounge access and higher rewards on United purchases, despite its steep annual fee. Both cards cater to different needs, with the United Quest℠ Card being more suitable for moderate spenders and the United Club℠ Infinite Card appealing to elite travelers seeking premium perks.
