I’ve logged almost a million United miles. Here are the credit cards I’d actually suggest

Over the past two decades, I’ve flown nearly a million miles with United, taken more than 475 United flights and spent 10 straight years as a Premier 1K member. That experience has made one thing clear: the right credit card benefits can materially improve the way you travel. Free checked bags, priority boarding, MileagePlus mile earnings and Premier Qualifying Points (PQPs) toward elite status all matter, and for frequent flyers, United Club access can be especially useful.

I’ve been a MileagePlus member since 2008 and have put the program through just about every test possible. I’ve redeemed hundreds of thousands of miles, used PlusPoints for upgrades, earned PQPs through credit card spending and spent countless hours in United Clubs and Polaris lounges. From short domestic hops to ultra-long-haul international trips, I’ve seen firsthand which benefits are worth paying for.

You don’t need to fly as much as I do to get value from a United credit card, though. Occasional travelers may be satisfied with perks like free checked bags and priority boarding, while frequent flyers may care more about lounge access, elite-status help and premium extras. Business owners and people who prefer flexible rewards also have solid options.

After years of flying United and testing these cards in real life, I’ve put together the best United Airlines credit cards, with a focus on practical value, useful perks and CNN Underscored’s credit card methodology:

United Gateway℠ Card: Best no-annual-fee United credit card

• Why it stands out: One of the few airline cards with no annual fee that still earns bonus miles in everyday categories.
• Intro offer: Earn up to 50,000 United MileagePlus bonus miles after spending $1,000 on qualifying purchases in the first three months after opening an account (40,000 miles, plus 10,000 more with an authorized user*).
• Annual fee: $0.
• Intro APR: 0% intro APR on purchases for 12 months from account opening (19.99% to 28.49% variable after that).
• Who it’s for: Occasional United flyers who want to earn MileagePlus miles without paying an annual fee.

The United Gateway Card earns bonus miles at gas stations, on local transit and commuting, and on United purchases, which is a useful mix for a no-fee airline card. It does not include a free checked bag, but it still makes a strong entry point into the MileagePlus program for light packers or infrequent travelers.

If you only fly United a few times a year and want to build miles for future trips without an annual fee, this card does the job well. Travelers who check bags often will probably want a higher-tier United card instead.

United Explorer℠ Card: Best starter card for United flyers

• Why it stands out: A strong blend of travel benefits, including a free checked bag and lounge passes, at a manageable annual fee.
• Intro offer: Earn up to 80,000 United MileagePlus bonus miles after spending $3,000 on qualifying purchases in the first three months after opening an account, plus a $0 annual fee for the first year (70,000 miles, plus 10,000 more with an authorized user*).
• Annual fee: $0 intro annual fee for the first year, then $150.
• Intro APR: Not currently offered.
• Who it’s for: Travelers who fly United a few times a year and want meaningful perks without premium-card pricing.

The United Explorer Card covers the basics: a free first checked bag for you and one companion, priority boarding, two United Club one-time passes each year, and 2x earnings on United purchases, dining and hotel stays booked directly.

It also includes a Global Entry, TSA PreCheck or NEXUS credit of up to $120 every four years, expanded award availability and 25% back on in-flight purchases. For a card with a modest annual fee, those benefits can be enough to justify keeping it with just a few round trips per year.

United Quest℠ Card: Best overall value for most United flyers

• Why it stands out: A well-balanced mix of price and benefits, with strong travel credits, free bags and annual award rebates.
• Intro offer: Earn 500 PQP after your first purchase and up to 90,000 bonus miles after spending $4,000 on purchases in the first three months your account is open (80,000 miles, plus 10,000 more with an authorized user*).
• Annual fee: $350.
• Intro APR: Not currently offered.
• Who it’s for: United flyers who travel several times a year and want valuable perks without moving up to a premium lounge card.

The United Quest Card includes two free checked bags for you and a companion, priority boarding, up to $125 in annual United purchase credits and an annual 10,000-mile award rebate that can be earned twice: once automatically and once more after spending $20,000 in a calendar year.

You’ll earn 4 miles per dollar on United purchases and 2 miles per dollar on dining and general travel, along with the ability to earn PQPs through spending. Expanded award availability, no foreign transaction fees and 25% back on in-flight purchases add to the value, which is why this card stays in my wallet.

For many MileagePlus loyalists, this card delivers the best ongoing value without stepping into premium-card territory.

United Club℠ Card: Best for United Club lounge access

• Why it stands out: Full United Club membership plus premium United benefits that frequent travelers can use on every trip.
• Intro offer: Earn up to 100,000 United MileagePlus bonus miles after spending $5,000 on qualifying purchases in the first three months after opening an account (90,000 miles, plus 10,000 more with an authorized user*).
• Annual fee: $695.
• Intro APR: Not currently offered.
• Who it’s for: United loyalists who want unlimited lounge access and top-tier travel perks.

The United Club Card’s main attraction is full United Club membership for you and eligible guests when you fly United. It also comes with Premier Access benefits, including priority check-in, screening where available, boarding and baggage handling.

The top United card earns 5 miles per dollar on United purchases and offers improved award pricing on select United flights, along with expanded award availability. Two free checked bags, a Global Entry or TSA PreCheck credit and no foreign transaction fees round out the package.

If lounge access and priority service matter most to you, this is the most complete United credit card available.

United℠ Business Card: Best United card for business owners

• Why it stands out: Strong earning categories for business spending, plus solid United travel perks.
• Intro offer: Earn up to 100,000 United MileagePlus bonus miles and 2,000 PQP after spending $5,000 on qualifying purchases in the first three months after opening an account (90,000 miles, plus 10,000 more with an authorized user*).
• Annual fee: $150.
• Intro APR: Not currently offered.
• Who it’s for: Small-business owners who want to earn United miles on everyday operating costs while getting travel benefits.

The United Business Card earns 2 miles per dollar on United, dining, gas stations, office supply stores and local transit, which fits many business budgets well. It also offers a free checked bag for you and a companion, priority boarding and two United Club one-time passes each year.

Other benefits include a $125 annual United purchase credit with straightforward spending requirements, expanded award availability, 25% back on in-flight purchases, no foreign transaction fees and PQP earning from card spend.

For entrepreneurs who travel on United for work, this card offers solid value.

Chase Sapphire Reserve®: Best premium travel card for United flyers who want flexibility

• Why it stands out: Premium perks, transferable points and strong travel protections, all of which work well with United and other Star Alliance carriers.
• Intro offer: Earn 100,000 bonus points after spending $6,000 on purchases in the first three months from account opening.
• Annual fee: $795.
• Intro APR: Not currently offered.
• Who it’s for: Frequent travelers who want premium perks and flexible points instead of being tied to one airline.

The Chase Sapphire Reserve is another card I’ve added to my wallet recently. It pairs well with United because it offers flexible, transferable points and elevated travel benefits. The annual fee is $795, but it can still make sense for frequent travelers who want more than a single-airline card can offer.

Our senior money editor and credit card expert Alberto Riva, who also holds the card, has examined its many advantages closely and found that the value can outweigh the cost. Cardholders get a $300 annual travel credit that automatically applies to a broad range of travel purchases, plus additional credits that can apply to certain restaurants and hotels, along with a Global Entry or TSA PreCheck credit. The card also includes Priority Pass lounge access and entry to Air Canada Maple Leaf Lounges when traveling on United, Air Canada or other Star Alliance carriers.

The Sapphire Reserve also includes strong travel protections that can help when flights are delayed or canceled. On top of that, it offers elevated earnings in categories frequent travelers care about: 8 points per dollar on bookings through the Chase Travel portal, 4 points per dollar on flights and hotels booked directly with the provider, and 3 points per dollar on dining. Since Chase Ultimate Rewards® points transfer to United MileagePlus® at a 1:1 ratio, those points can be just as useful as United miles.

Which credit card is best for United flyers?

For occasional travelers who still want benefits like a free checked bag, I’d point to the United Quest Card, which often delivers the best overall value without requiring a top-tier annual fee.

If your main goal is earning MileagePlus Premier status, the Quest’s ability to earn PQPs — or pairing a United card with strong everyday spending categories — can help you move up more quickly.

Frequent travelers who want United Club access and premium ground service should consider the United Club Card, which is the only United co-branded card that includes full United Club membership.

If you’re like me and prefer flexibility over United Club access, though, the Chase Sapphire Reserve offers transfer partners, dining bonuses and broader lounge access around the world, while still pairing well with MileagePlus.

How we evaluate credit cards

According to CNN Underscored’s credit card methodology, we look at cards based on a range of factors that reflect how they perform for real users, not just credit card enthusiasts. The main factors include:

• Earning rate versus redemption value: A strong earning rate matters only if the rewards are valuable. We weigh both sides to judge a card’s overall value.
• Fees against benefits: We compare annual fees with the concrete value of the card’s perks, including travel benefits, statement credits and insurance protections.
• Welcome offer: A generous welcome offer can make a card worth applying for, but only if the spending requirement is realistic.
• Ease of redemption: We consider how easy it is to use rewards and whether transferable points have useful airline and hotel partners.
• Travel and purchase protections: Trip delay and interruption coverage, baggage protection and rental car insurance can make a travel card stand out, as can purchase protections such as extended warranties and price protection.
• Interest rates and balance transfer offers: While we advise avoiding interest, we still evaluate 0% APR introductory offers for people who want to manage debt strategically.

FAQs

Absolutely, and it’s one of my favorite ways to earn United miles without flying. Eligible Chase Ultimate Rewards points transfer to United MileagePlus at a 1:1 ratio. Cards such as the Chase Sapphire Reserve let you earn points on everyday spending and move them to United when you’re ready to book. Before transferring, it’s smart to check award availability, since transfers usually can’t be reversed.

Yes. Several United credit cards offer access to expanded award availability on United-operated flights that isn’t always available to general MileagePlus members. I’ve found this especially useful on popular routes and during busy travel periods. Some cards also provide discounts on eligible award flights, which can make your miles go further.

Yes, and that’s one of the biggest strengths of MileagePlus. United is part of Star Alliance, so you can redeem miles for flights on partners such as Lufthansa, ANA and Singapore Airlines, subject to availability. Partner awards can be especially valuable for international travel, though it’s still smart to compare mileage costs and taxes before booking.
