United's most premium co-branded credit card, the Chase United Club Card, carries a $695 annual fee and a limited-time welcome offer: 90,000 MileagePlus miles after spending $5,000 in the first three months, plus another 10,000 miles for adding an authorized user. At a typical valuation of about 1.3 cents per mile, that bonus is worth roughly $1,300 — comfortably more than the fee. Authorized users cost nothing to add, though they don't get lounge access.

The headline perk is a United Club membership for as long as you hold the card — including one guest plus kids under 18. Standalone United Club memberships cost $750, so the card effectively undercuts the lounge on price before you count anything else. United has more than 45 clubs, concentrated at hubs like Chicago, Denver, Houston, Newark and San Francisco. Spend $50,000 a year on the card, or hold Premier Gold status, and the membership upgrades to all-access, opening up Star Alliance lounges too.

On the flying side, the card covers first and second checked bags for you and a companion, knocks 10% or more off award flights, and grants Premier Access services. Earning is respectable: 5x miles on United purchases, 2x on most other travel and dining, 1x elsewhere. There are also credits for Global Entry or TSA PreCheck, complimentary IHG Platinum status, and over $875 in annual partner credits across rideshare and Instacart — handy if you'd use them, useless if you wouldn't.

Two features make this card stand out for people chasing status. Cardholders get 1,500 Premier Qualifying Points a year just for holding the card, plus one PQP for every $15 spent, capped at 28,000 — enough to spend your way most of the way to Premier 1K. And every $20,000 spent in a calendar year earns a 10,000-mile discount on an award ticket, up to two per year.

The catch is eligibility and the broader MileagePlus landscape. Chase's 5/24 and 2/30 rules apply, and you can't get the bonus if you've had it in the past 24 months — though other United cards don't block you. More importantly, United has quietly made having a co-branded card close to essential: cardmembers earn an extra 3x miles on United spending regardless of elite tier, and award pricing and saver-level availability are notably better for cardholders. Most Polaris business class award seats go only to MileagePlus members in the first place.

Who's this actually for? Frequent United flyers who pass through a hub with a club and check bags will recoup the fee easily. If you fly United twice a year through an airport without a lounge, cheaper cards or a general travel rewards card will serve you better.
