The Chase United Club℠ Credit Card is a premium airline credit card designed for frequent United Airlines travelers who want unlimited United Club access, valuable travel credits, free checked bags, Premier Access travel services, elevated United MileagePlus earning opportunities and benefits that can help travelers pursue United Premier status. The card carries a $695 annual fee, but its premium benefits are designed to provide significant value to frequent United flyers who can consistently use the included lounge membership, travel credits, baggage benefits and other perks. The card is substantially more expensive than lower-tier United credit cards, but it also provides a much broader collection of premium travel benefits, making it an especially interesting option for consumers who fly United regularly and want a dedicated United Airlines rewards card.

- High Spending Needed to Maximize Rewards: Cardholders who do not spend regularly on travel, dining, and other eligible purchases may find it difficult to earn enough rewards to offset the annual fee.

Up to 90,000 Bonus Miles
The current welcome opportunity allows eligible new cardmembers to earn 80,000 United MileagePlus bonus miles after spending $5,000 on purchases during the first three months, with an additional 10,000 bonus miles available after adding an authorized user within the first three months, creating a potential total of 90,000 bonus miles. The spending requirement is higher than many mainstream rewards cards, so applicants should make sure they can meet the requirement through normal planned purchases. Consumers should never take on unnecessary debt simply to earn a credit card bonus, and applicants should review the current offer carefully because introductory promotions can change.
Unlimited United Club Access
The primary attraction of the United Club Card is unlimited United Club access, which can provide substantial value to frequent United travelers who regularly pass through airports with United Club locations. United Club lounges can provide travelers with a quieter place to relax before flights along with complimentary refreshments, Wi-Fi and other amenities. For a frequent flyer who would otherwise purchase lounge memberships or pay for individual airport lounge access, the included membership can represent a significant portion of the card’s annual value.
United Club All Access
Qualified cardmembers can receive United Club All Access after achieving United Premier Gold status or meeting the applicable annual spending requirement on the card. The expanded membership provides broader guest privileges and access to participating Star Alliance partner lounges under the applicable terms. This benefit is particularly valuable for frequent travelers who already qualify for higher United elite status or who can comfortably reach the required spending level without making unnecessary purchases.
First and Second Checked Bags Free
The United Club Card provides first and second checked bags free for the primary cardmember and one eligible companion traveling on the same reservation when the applicable United flight requirements are satisfied. This benefit can be especially valuable for families and travelers who frequently check luggage because baggage charges can become expensive over multiple trips. Consumers who regularly check two bags on United flights may find that the annual baggage savings alone contribute meaningfully toward offsetting the card’s annual fee.
Premier Access Travel Services
Premier Access provides eligible cardmembers with priority airport services that can include dedicated check-in, priority security where available, priority boarding and expedited baggage handling. For frequent travelers, the value of Premier Access is not limited to direct financial savings because priority services can reduce airport waiting times and make the overall travel experience more convenient. Travelers who frequently fly during busy periods may find these benefits particularly useful.
11x Miles on Eligible United Flights
The United Club Card can earn 11x total miles on eligible United flights, combining MileagePlus earning with the card’s rewards earning. This makes the card especially attractive to travelers who spend significant amounts on United airfare throughout the year. The actual MileagePlus earning rate can depend on the traveler’s United status and ticket type, so consumers should review the applicable MileagePlus rules when calculating their expected rewards.
5x Miles on Other United Purchases
Eligible United purchases outside the airfare category can earn 5x miles, providing additional rewards for expenses such as qualifying seat upgrades, Economy Plus purchases, inflight purchases and other eligible United services. This makes the United Club Card particularly effective as a dedicated United spending card because cardmembers can earn elevated rewards on multiple types of United-related purchases rather than earning a higher rate only on airfare.
5x Miles on Renowned Hotels and Resorts
Cardmembers can earn 5x miles on qualifying Renowned Hotels and Resorts bookings made through the designated United program, while eligible reservations can also qualify for an annual statement credit. This feature adds a hotel component to an otherwise airline-focused credit card. Travelers who regularly stay at participating properties may receive considerable value from this benefit, while consumers who rarely use the participating hotel program should assign a lower personal value to the benefit.
2x Miles on Travel
The United Club Card earns 2x miles on eligible travel purchases, providing a broader rewards category beyond United Airlines. Qualifying travel can include airfare outside the card’s United bonus category, hotels, rental cars, cruises, trains, taxis, rideshare services, tolls and other eligible transportation expenses. This gives the card some versatility for consumers who regularly travel, although other premium travel cards may offer stronger rewards on general travel purchases.
2x Miles on Dining
Eligible dining purchases earn 2x United MileagePlus miles, giving cardmembers an additional everyday rewards category. This can be useful for frequent travelers who spend significant amounts at restaurants and other qualifying dining establishments. The dining category is not the card’s strongest feature, but it provides a useful way to continue earning MileagePlus miles when consumers are not purchasing United flights.
1x Mile on Other Purchases
Other eligible purchases generally earn 1 United MileagePlus mile per dollar, making the United Club Card less attractive as a single-card solution for consumers with large amounts of non-bonus spending. Consumers who want to maximize their total credit card rewards may want to use a separate card for everyday purchases that offers a stronger flat-rate return. The United Club Card is best viewed as a specialized travel card rather than a universal cash-back replacement.
More Than $875 in Annual Partner Credits
The card currently provides more than $875 in potential annual partner credits when all eligible benefits are fully used. These benefits can include credits associated with hotels, rideshare services, rental cars, Instacart and JSX. The important point is that the advertised value represents the maximum potential benefit rather than guaranteed cash savings because each credit has specific requirements. Consumers should only count a credit toward their personal annual-fee calculation if they would naturally use the applicable service.
$200 Renowned Hotels and Resorts Credit
Cardmembers can receive up to $200 in annual statement credits for qualifying hotel stays booked and prepaid through the designated Renowned Hotels and Resorts program. This can be a valuable benefit for travelers who already stay at participating properties. Consumers who would not otherwise book these hotels should not treat the full $200 as guaranteed savings because using a credit for a purchase that would not otherwise have been made does not create the same financial value as reducing an expense already in the travel budget.
$150 Rideshare Credit
The card provides up to $150 in rideshare credits each calendar year under the current benefit structure. The credits are distributed throughout the year rather than provided as one unrestricted annual credit, so cardmembers need to use the benefit during the applicable monthly periods to capture the full value. Frequent rideshare users may find this benefit easy to use, while consumers who rarely use rideshare services may receive little practical value from it.
$100 Avis and Budget Travel Credit
Cardmembers can receive up to $100 in United TravelBank cash each anniversary year when they complete qualifying Avis or Budget rental-car bookings through the designated United booking channel and pay with the United Club Card. Frequent travelers who already rent from these companies can potentially use the credit naturally. Travelers who primarily rent from other companies should assign little or no value to the benefit when deciding whether the card’s annual fee is worthwhile.
Up to $240 Instacart Credits
The United Club Card offers up to $240 in Instacart credits each calendar year under the current benefit structure, along with qualifying Instacart membership benefits. The credits can be useful for consumers who already use Instacart for grocery and household deliveries. Because the benefit involves monthly credits and specific eligibility requirements, cardholders should monitor the benefit carefully to avoid allowing available credits to go unused.
$200 JSX Credit
The card provides up to $200 in statement credits each anniversary year on eligible JSX purchases. This can be valuable for travelers who use JSX, but the benefit has limited practical value for consumers who never fly JSX. As with the other partner benefits, the correct way to evaluate this credit is based on whether the cardholder would naturally make eligible purchases rather than simply adding the maximum advertised credit to the card’s theoretical value.
1,500 Annual Card Bonus PQP
The United Club Card provides 1,500 Card Bonus Premier qualifying points each year under the applicable program rules. This benefit can provide a valuable head start for travelers pursuing United Premier status because it allows eligible cardmembers to begin the year with additional qualifying points. The benefit is primarily valuable to United loyalists who actively pursue elite status and less important to travelers who have no interest in United Premier benefits.
Up to 28,000 PQP Through Spending
Cardmembers can earn 1 Premier qualifying point for every $15 spent on eligible purchases, up to 28,000 PQP per calendar year. This creates a potential pathway toward United Premier status through credit card spending, although reaching the maximum would require a very substantial amount of spending. Consumers should not spend beyond their normal budget simply to earn elite-qualifying points because the interest or opportunity cost associated with unnecessary spending can outweigh the value of United status.
10,000-Mile Award Flight Discounts
Cardmembers can earn a 10,000-mile award-flight discount after spending $20,000 during a calendar year, with the opportunity to earn up to two discounts annually after reaching the higher qualifying spending level. These discounts can provide substantial value to travelers who regularly redeem MileagePlus miles for United award flights. Consumers should evaluate the benefit based on their normal travel and redemption patterns rather than spending money solely to trigger the discount.
25% Back on United Inflight Purchases
The United Club Card provides 25% back as a statement credit on eligible United inflight food, beverage and Wi-Fi purchases and qualifying premium drinks purchased at United Clubs. While this benefit is not as valuable as the card’s lounge membership or free checked bags, it can provide useful savings for frequent flyers who regularly purchase these services.
Global Entry, TSA PreCheck and NEXUS Credit
The card provides up to $120 every four years toward Global Entry, TSA PreCheck or NEXUS application fees when the eligible fee is charged to the card. This can be valuable for frequent travelers because trusted-traveler programs can make airport security and border processing more convenient. The credit is not an annual benefit, but it can still reduce the cost of enrollment when the cardmember or an eligible traveler needs to renew or apply.
IHG One Rewards Platinum Elite Status
The card provides access to IHG One Rewards Platinum Elite status under the applicable terms. The status can provide additional hotel benefits and recognition when staying at participating IHG properties. United travelers who also regularly stay at IHG hotels can therefore receive value from the card beyond airline travel.
Avis President’s Club Status
Eligible cardmembers can receive Avis President’s Club status, providing access to enhanced rental-car benefits under the applicable Avis program terms. Frequent Avis renters may find the status valuable because it can provide additional convenience and potential upgrades when renting vehicles. Consumers who rarely rent from Avis should place little value on this benefit when calculating the card’s overall worth.
No Foreign Transaction Fees
The United Club Card has no foreign transaction fees, making it a practical payment option for international travel. This allows cardmembers to use the card abroad without paying a separate foreign transaction fee on eligible purchases. The benefit is particularly useful for United travelers who frequently fly international routes or use United’s Star Alliance network.
Is the $695 Annual Fee Worth It?
The $695 annual fee is significant, but the card can justify the cost for frequent United travelers who regularly use its premium benefits. The United Club membership alone can represent substantial value for travelers who would otherwise purchase lounge access, while free checked bags, Premier Access, annual partner credits, MileagePlus benefits and PQP opportunities can add considerable additional value. The important issue is that the card’s advertised maximum value does not necessarily equal every cardmember’s real-world value. A traveler who never uses Instacart, JSX or participating hotels should not count those credits as full savings, while a traveler who uses all of them naturally may find the card’s effective cost considerably lower.
Example of Potential Annual Value
Consider a frequent United traveler who uses United Club lounges throughout the year, regularly checks two bags, uses eligible rideshare services, makes qualifying hotel bookings, uses Instacart and occasionally rents from Avis or Budget. That traveler could potentially receive more than $875 in annual partner credits before assigning any value to lounge access, checked-bag savings, Premier Access, MileagePlus miles, PQP and other benefits. The actual value depends entirely on the traveler’s personal behavior, but the example demonstrates why the card can make financial sense for a high-frequency United customer while being much less attractive to an occasional flyer.
Who Should Apply for the Chase United Club℠ Credit Card?
The Chase United Club Card is best suited to frequent United Airlines travelers who regularly use United Club lounges, check bags, value Premier Access, want to earn United MileagePlus miles, are interested in pursuing Premier status and can naturally use several of the card’s annual credits. It can also be attractive to business travelers who spend heavily on United flights and to families who frequently check multiple bags. Consumers who already know they will use United Club access several times throughout the year may be particularly well positioned to benefit from the card.
Who Should Avoid the Chase United Club℠ Credit Card?
The United Club Card may not be a good fit for occasional United travelers, consumers who rarely use airport lounges, travelers who primarily fly other airlines, consumers who dislike premium annual fees and people who cannot use the card’s specialized annual credits. Someone who flies United only a few times each year may be better served by a lower-fee United credit card. The same is true for consumers who want flexible cash-back rewards rather than airline-specific MileagePlus miles.
Chase United Club℠ Rewards Strategy
The most effective rewards strategy is to use the United Club Card for eligible United flights and United purchases, qualifying travel, dining and the card’s specialized partner benefits while using another rewards card for purchases that would earn only 1x MileagePlus mile. Cardmembers should also monitor the annual credits throughout the year and activate benefits that require enrollment. Travelers pursuing United Premier status should track their PQP progress and determine whether card spending naturally supports their status goals without creating unnecessary expenses.
How United MileagePlus Miles Work
The United Club Card earns United MileagePlus miles rather than traditional cash-back rewards, so the ultimate value depends on how the cardmember uses those miles. MileagePlus miles can be redeemed for eligible United award flights and other qualifying travel opportunities. Redemption value can vary based on destination, travel dates, cabin class, availability and the specific award being booked. Travelers who understand how to maximize United award redemptions can potentially receive significantly more value than consumers who redeem miles without considering the available options.
Chase United Club for Families
The United Club Card can be particularly valuable for families who regularly travel on United because the primary cardmember and one eligible companion can receive first and second checked bags free on qualifying United flights. The potential savings can become substantial when a family takes multiple trips per year. United Club access can also make airport travel more comfortable, although families should understand the applicable guest policies because standard United Club access does not necessarily provide unlimited lounge access for every member of a large family.
Chase United Club for Frequent Travelers
Frequent United travelers are the card’s ideal audience because the card’s premium benefits become more valuable with repeated use. A traveler who flies United frequently can use United Club lounges, free checked bags, Premier Access, elevated United rewards, annual credits and PQP benefits throughout the year. The more often a cardmember naturally uses these benefits, the easier it becomes to offset the $695 annual fee.
Chase United Club vs. Chase United Quest℠ Credit Card
The United Quest Card has a lower annual fee and is designed for travelers who want valuable United benefits without paying for the premium Club Card. Quest provides several useful United travel benefits, while the United Club Card focuses more heavily on unlimited lounge access, premium travel benefits, extensive credits and elite-status opportunities. Consumers who fly United regularly but do not need unlimited United Club access may find the Quest more economical, while frequent United travelers who value lounge access may find the Club Card’s additional benefits worth the higher cost.
Chase United Club vs. Chase United Explorer℠ Credit Card
The United Explorer Card has a substantially lower annual fee and is intended for travelers who want basic United travel benefits such as a free first checked bag, priority boarding and limited United Club passes. The United Club Card costs much more but provides unlimited United Club access, first and second checked bags, additional credits and significantly more premium travel benefits. Occasional United flyers may receive better value from Explorer, while frequent United travelers who regularly use lounges may find the Club Card more compelling.
Chase United Club vs. Flexible Travel Credit Cards
The United Club Card is highly specialized, while premium general travel cards are typically designed to provide benefits across multiple airlines, hotels and travel providers. A traveler who flies United almost exclusively may benefit more from the United-specific rewards and lounge access, while someone who frequently switches between airlines may prefer a flexible travel card. The decision should depend on airline loyalty, lounge usage, annual travel frequency and the consumer’s ability to use the specialized credits.
Credit Score Needed for the Chase United Club℠ Credit Card
The United Club Card is generally intended for consumers with strong credit profiles, although there is no specific credit score that guarantees approval. Chase can consider an applicant’s credit history, payment record, existing debt, income, utilization, recent applications and other information. A strong credit score can improve approval odds, but applicants should evaluate their entire financial profile before applying for a premium card with a $695 annual fee.
Does the Chase United Club Card Have an APR?
Yes, the card has a variable regular APR that can be substantial, making it important for cardmembers to avoid carrying unnecessary balances. Premium travel rewards can quickly lose their value when interest charges accumulate, so consumers should ideally pay the statement balance in full each month. The card should be used primarily for rewards and travel benefits rather than as a high-cost source of long-term borrowing.
Is the Chase United Club Card Good for Everyday Spending?
The card is strongest for United purchases, eligible travel and dining, while other purchases generally earn 1x mile. Consumers who want maximum rewards on everyday purchases may therefore benefit from pairing the card with another credit card offering stronger flat-rate rewards. The United Club Card should generally be viewed as a premium United travel card rather than a universal everyday spending card.
Is the Chase United Club Card Good for Travel?
The Chase United Club Card is exceptionally strong for United-focused travel because it combines unlimited United Club access, free checked bags, Premier Access, elevated United rewards, travel credits, award-flight discounts and opportunities to earn Premier qualifying points. The lack of foreign transaction fees also makes it useful for international travel. Consumers who primarily fly United can potentially receive significant value from the card, especially when they use multiple benefits throughout the year.
How to Apply for the Chase United Club℠ Credit Card
Consumers should review the current welcome offer, annual fee, rewards rates, United Club rules, annual credits, APR and eligibility requirements before applying. The current introductory opportunity includes 80,000 bonus miles after meeting the required spending threshold and an additional bonus opportunity for adding an authorized user. Applicants should only pursue the welcome bonus if they can comfortably meet the spending requirement through normal purchases and should avoid taking on debt simply to earn rewards.
Tips for Getting the Most Value
To maximize the Chase United Club Card, use it for eligible United airfare, United purchases, qualifying travel and dining, take advantage of the free checked bags, use United Club lounges whenever practical, enroll in benefits that require activation, use rideshare credits before they expire, take advantage of qualifying hotel credits, use eligible rental-car credits, use Instacart credits if they fit your normal household spending, consider the JSX credit if applicable, use the Global Entry or TSA PreCheck credit when eligible, monitor PQP progress when pursuing United status and use award-flight discounts when they provide meaningful mileage savings.
Important Considerations Before Applying
The most important consideration is whether your normal travel habits justify a $695 annual fee. Consumers should not calculate the card’s value by simply adding every available credit together because several benefits require specific purchases, enrollment or participation in particular programs. Applicants should consider how often they fly United, how often they use United Club lounges, whether they check bags, whether they value Premier Access, whether they pursue United Premier status and whether they can naturally use the available annual credits. Consumers should also review the current card terms because premium card benefits and welcome offers can change.
Is the Chase United Club℠ Credit Card Worth It?
For frequent United Airlines travelers, the Chase United Club Card can be worth the $695 annual fee, particularly when the cardmember regularly uses United Club access, free checked bags and multiple annual credits. The potential value becomes even greater for consumers who pursue United Premier status because the card can provide annual PQP and additional opportunities to earn qualifying points through spending. The card is less compelling for occasional travelers who rarely use lounges or specialized partner benefits. The right question is not whether the card has enough advertised benefits to justify $695, but whether the individual cardmember will actually use enough of those benefits to create more than $695 in real-world value.

Bottom Line
The Chase United Club℠ Credit Card is a premium airline credit card built for travelers who want a comprehensive United Airlines travel experience rather than a basic rewards card. Its combination of unlimited United Club access, up to 90,000 bonus miles, elevated United flight rewards, first and second free checked bags, Premier Access, annual partner credits, Premier qualifying points, award-flight discounts, hotel and rental-car benefits and no foreign transaction fees makes it a powerful option for committed United MileagePlus members. The $695 annual fee is the biggest drawback, and travelers should carefully calculate their personal value rather than assuming every advertised benefit will be fully useful. For frequent United Airlines travelers who naturally use airport lounges, check bags, use travel credits and pursue United status, however, the Chase United Club Card can deliver substantial annual value and is one of the strongest premium United credit cards available in 2026.
