United credit cards are built around airline rewards, but the right one depends on how much you fly and what you spend on
United offers five main credit cards through Chase, each with different annual fees, sign-up bonuses, and earning rates. The "best" card is not the same for everyone — a frequent business traveler gets different value from a cardholder who takes one vacation a year. This guide walks through what each card offers, what it costs, and who actually comes out ahead with each one.
All United cards earn miles on purchases and give you checked baggage benefits. The main differences are the annual fee, the sign-up bonus structure, the earning rate on different spending categories, and perks like seat upgrades and lounge access. You need to know your own spending pattern and travel frequency before you decide which card makes financial sense for you.
Key Takeaways
- United's five cards range from no annual fee to $650 per year, and the higher-fee cards offer larger sign-up bonuses and more premium perks.
- The card that saves you the most money depends on whether you spend more on travel, dining, or everyday purchases, and how often you actually use airline miles.
- Every United card includes a free checked bag for you and one companion on United flights, which alone can save $60 to $70 per round trip.
- Sign-up bonuses typically require you to spend a set amount within three months, so you should only open a card if you can meet that spending threshold without overspending.
- United miles expire after 18 months of account inactivity, so the card only makes sense if you plan to use the miles or keep the account active regularly.
The United Gateway Card: No annual fee, basic rewards
The United Gateway Card has no annual fee and earns 1 mile per dollar on all purchases. You get the free checked bag benefit and access to United's website for booking, but no sign-up bonus and no premium perks like seat upgrades or lounge access.
This card makes sense if you fly United occasionally but do not want to pay an annual fee. You build miles slowly, but you pay nothing to hold the card. The free checked bag alone saves money if you fly even once a year. If you spend $10,000 a year on the card, you earn 10,000 miles — enough for a domestic award flight on many routes, though availability varies by airport and season.
The United Explorer Card: The middle ground for regular travelers
The United Explorer Card costs $99 per year and comes with a sign-up bonus of 50,000 miles after you spend $3,000 in the first three months. You earn 2 miles per dollar on United purchases and dining, and 1 mile per dollar on everything else. You get the free checked bag, seat upgrade certificates, and access to United Club passes (limited, not unlimited).
This card works well if you fly United at least once or twice a year and eat out regularly. The $99 annual fee is offset by the free checked bag benefit and the sign-up bonus. If you meet the spending requirement easily, you start with 50,000 miles — roughly a domestic round trip or a partial international flight. The 2x earning on dining means a household that spends $500 a month on restaurants earns an extra 12,000 miles per year compared to the Gateway card.
The seat upgrade certificates are real value if you book economy fares regularly. United gives you two certificates per year, and they can move you to premium economy or business class depending on availability. On a $400 economy ticket, that upgrade might be worth $200 to $400 in cabin value.
The United Club Infinite Card: Premium perks and lounge access
The United Club Infinite Card costs $650 per year and includes unlimited access to United Club lounges (worth roughly $100 per visit if you bought day passes). The sign-up bonus is 70,000 miles after $5,000 in spending. You earn 2 miles per dollar on United purchases and dining, and 1 mile per dollar elsewhere.
This card is for people who fly United frequently — typically at least monthly — and value lounge access. The unlimited lounge pass alone justifies the fee if you use it more than six or seven times a year. You also get four seat upgrade certificates per year instead of two, and priority boarding. The 70,000-mile sign-up bonus is larger than the Explorer card's, but the $650 annual fee is substantial.
If you fly United 12 times a year and visit the lounge twice per trip, you use the lounge 24 times annually. At $100 per day pass, that is $2,400 in value — far more than the $650 fee. But if you fly four times a year and never use the lounge, the card costs you money compared to the Explorer card.
The United Business Card and United Business Infinite Card: For business spending
United offers two business cards: the United Business Card ($99 annual fee) and the United Business Infinite Card ($500 annual fee). Both earn miles on business purchases and include the free checked bag. The Business Infinite includes lounge access and higher earning rates on United purchases.
These cards make sense if you put significant business expenses on your card — flights, hotels, rental cars, office supplies. The earning rates and perks are similar to the consumer cards, but the spending categories are tailored to business use. If your company reimburses you for travel, the miles go into your personal account, so you build a balance quickly. The $99 Business Card is a good entry point if you travel for work occasionally; the $500 Business Infinite is for people who fly constantly and want lounge access.
How to compare the cards side by side
| Card | Annual Fee | Sign-Up Bonus | Earning Rate | Checked Bag | Lounge Access |
|---|---|---|---|---|---|
| Gateway | $0 | None | 1x all purchases | Yes | No |
| Explorer | $99 | 50,000 miles | 2x United & dining, 1x other | Yes | Limited passes |
| Club Infinite | $650 | 70,000 miles | 2x United & dining, 1x other | Yes | Unlimited |
| Business | $99 | 50,000 miles | 2x United & business, 1x other | Yes | No |
| Business Infinite | $500 | 70,000 miles | 2x United & business, 1x other | Yes | Unlimited |
To decide which card makes sense for you, start with your annual spending and flight frequency. If you spend less than $3,000 per year on United and related categories, the Gateway card's zero fee is hard to beat. If you spend $3,000 to $10,000 and fly a few times a year, the Explorer card's $99 fee and 50,000-mile bonus usually pay for themselves. If you fly monthly and use lounges, the Club Infinite's $650 fee becomes reasonable.
The sign-up bonus is a one-time boost, not an ongoing benefit. Do not open a card just to get the bonus if you cannot meet the spending requirement naturally. Opening a card and then overspending to hit the bonus usually costs more than the miles are worth.
What to know about United miles and redemption
United miles do not have a fixed dollar value — what they are worth depends on the flight you book. A domestic round trip might cost 25,000 to 50,000 miles depending on the route and season. An international flight can cost 60,000 to 150,000 miles. Premium cabin upgrades cost extra miles on top of the base award price.
Miles expire 18 months after your last account activity. Activity includes earning miles, redeeming miles, or even just logging into your United account. If you open a card and never fly or use the miles, they will disappear. This is why the card only makes sense if you plan to use United regularly or at least keep the account active by logging in or taking one flight per year.
Award availability varies by route and season. Popular routes in peak travel times may have few or no award seats available, even if you have enough miles. Off-peak travel and less popular routes have better availability. This is not a United-specific issue — all airlines manage award inventory this way.
Frequently Asked Questions
Can I hold more than one United credit card at the same time?
Yes, you can hold multiple United cards. Some people hold the Gateway card for everyday spending and the Explorer card for travel and dining to maximize earning. Chase has rules about how many cards you can open in a certain time period, so space out applications if you want more than one.
Do I have to fly United to make the card worth it?
No. You earn miles on all purchases, not just flights. The Explorer card earns 2x on dining, so if you eat out frequently, you build miles even if you do not fly. However, the annual fee only makes sense if you plan to redeem the miles eventually. If you never book a United flight, the miles sit unused and the fee is wasted.
What happens to my miles if I close the card?
Your miles stay in your United account — they do not disappear when you close the card. However, if you close the card and do not fly or log in for 18 months, the miles will expire. To keep them active, you need at least one account activity every 18 months.
Is the sign-up bonus worth opening a new card?
The sign-up bonus is worth it only if you can meet the spending requirement without changing your normal habits. If the Explorer card requires $3,000 in three months and you normally spend $1,000 per month, you will hit it naturally. If you normally spend $500 per month, you would have to overspend by $1,500 to may have access to — and overspending usually costs more than the miles are worth.
Which card should I pick if I only fly once a year?
The Gateway card with no annual fee is the safest choice. You get the free checked bag benefit, which saves money on that one trip. You earn 1 mile per dollar, which builds slowly but costs you nothing. If you decide to fly United more often later, you can upgrade to the Explorer card then.
