The best United card depends on how often you fly United and what you spend on outside of flights

United offers five main credit cards through Chase, and the "best" one is the one that pays you back more than its annual fee costs you. If you fly United multiple times a year and spend heavily on travel and dining, a premium card with a high annual fee might work. If you take one United flight every few years and want no annual fee, a basic card is the right choice. The decision comes down to three numbers: your annual United spending, how many miles you'd actually use, and whether the card's perks cover its fee.

This guide walks through each card's rewards structure, annual fees, and the specific situations where each one makes financial sense. You'll see the actual earning rates, the real dollar value of the perks, and how to calculate whether a card pays for itself in your situation.

Key Takeaways

  • United cards earn 2 to 4 miles per dollar on United purchases and 1 to 2 miles per dollar on dining and travel, depending on which card you choose.
  • Annual fees range from $0 to $650, and most premium cards include perks like free checked bags and United Club passes that offset part of the fee.
  • The United Explorer Card ($95 annual fee) is the entry point for frequent United flyers; the United Club Infinite ($650 annual fee) is for those who use airport lounges regularly and fly business or first class.
  • Comparing cards means calculating your own earning potential: multiply your annual United spending by the miles-per-dollar rate, then subtract the annual fee in dollar value.
  • Sign-up bonuses typically range from 50,000 to 150,000 miles, but these are one-time payouts and should not be the only reason to choose a card.

The five United cards and their annual fees

Chase issues the United MileagePlus cards under five tiers. The United Gateway Card has no annual fee. The United Explorer Card costs $95 per year. The United Explorer Card Business also costs $95 per year but is designed for business owners. The United Club Infinite Card costs $650 per year. The United Club Infinite Card Business also costs $650 per year.

For most people, the choice is between the Gateway (no fee) and the Explorer ($95 fee). The Club Infinite cards are for people who use airport lounges multiple times per month and regularly book premium cabin flights. If you fly United once or twice a year, the Gateway card is almost always the better choice. If you fly United four or more times per year and spend $10,000 or more annually on dining and travel, the Explorer card's perks usually cover the $95 fee.

Rewards rates: where you earn the most miles

The Gateway card earns 1 mile per dollar on all purchases. The Explorer card earns 2 miles per dollar on United purchases and United dining, 2 miles per dollar on all other dining and travel (hotels, rental cars, rideshare, transit), and 1 mile per dollar on everything else. The Club Infinite card earns 4 miles per dollar on United purchases, 3 miles per dollar on dining and travel, and 1 mile per dollar on everything else.

The difference between 1 mile and 2 miles per dollar is significant only if you spend heavily on dining and travel. If you spend $5,000 per year on dining and travel, the Explorer card earns you 10,000 extra miles compared to the Gateway card. At a typical redemption value of 1 cent per mile, that's $100 in value — enough to cover the $95 annual fee. If you spend $2,000 per year on dining and travel, the Explorer card earns you only 4,000 extra miles, or about $40 in value, which does not cover the fee.

Annual perks that reduce the effective cost

The Explorer card includes a $100 United travel credit that you can use toward airfare, seat upgrades, or baggage fees once per calendar year. This credit is not automatic — you must use it within the calendar year or it disappears. If you book at least one United flight per year, you can use this credit. The math is straightforward: $100 credit minus $95 annual fee equals $5 net cost.

The Club Infinite card includes a $100 United travel credit (same as Explorer), a $200 annual United Club pass credit, and a $100 annual dining credit through DashPass. The Club Infinite also includes a free checked bag for you and up to eight companions on United flights. If you use the Club Infinite lounge access at least once per month and take advantage of the travel and dining credits, the card can pay for itself. If you use the lounge fewer than four times per year, the card is unlikely to be worth the $650 fee.

Both the Explorer and Club Infinite cards include a free checked bag for you and up to eight immediate family members traveling on the same ticket. The Gateway card does not include this perk, so if you check a bag on United, you pay $35 per bag per direction. Over three round trips per year, that's $210 in checked bag fees — enough to make the Explorer card's $95 fee look cheap.

Sign-up bonuses and how to think about them

United cards typically offer sign-up bonuses of 50,000 to 150,000 miles when you spend a certain amount in the first three months. A 50,000-mile bonus is worth roughly $500 at typical redemption rates. A 100,000-mile bonus is worth roughly $1,000. These bonuses are real value, but they are one-time payouts. After you earn the bonus, the card's value depends entirely on its ongoing rewards rates and perks.

Do not choose a card based on the sign-up bonus alone. The bonus should be a reason to open the card now rather than later, but the card itself should make sense for your ongoing spending. If the Explorer card's ongoing rewards and perks do not justify the $95 annual fee, a 75,000-mile sign-up bonus does not change that calculation — it just delays the point at which the card stops paying for itself.

When to choose each card

Choose the Gateway card if: You fly United fewer than four times per year, or you fly United frequently but do not spend much on dining and travel outside of flights. The Gateway card's 1 mile per dollar on all purchases is simple, and the lack of an annual fee means you break even immediately.

Choose the Explorer card if: You fly United at least three times per year, or you spend $10,000 or more annually on dining and travel (including United flights). The $100 travel credit and free checked bag perk usually cover the $95 annual fee, and the 2x miles on dining and travel accelerate your earning.

Choose the Club Infinite card if: You fly United in business or first class at least twice per year, or you visit United Club lounges at least once per month. The $200 Club pass credit and $100 travel credit offset most of the $650 annual fee, and the 4x miles on United purchases add up quickly if you book premium cabins.

How to calculate the card that works for your situation

Start with your annual spending in three categories: United flights, dining, and all other travel (hotels, rental cars, rideshare, transit). Multiply each category by the miles-per-dollar rate for the card you are considering. Add those miles together, then multiply by 0.01 to convert miles to dollars (this assumes 1 cent per mile, which is a conservative estimate for most redemptions). Subtract the annual fee. If the result is positive, the card pays for itself.

Example: You spend $3,000 per year on United flights, $2,000 on dining, and $1,500 on other travel. With the Explorer card, you earn 2 miles per dollar on all three categories, for a total of 13,000 miles, or $130. Subtract the $95 annual fee, and you net $35 in value. With the Gateway card, you earn 1 mile per dollar on all categories, for a total of 6,500 miles, or $65. The Explorer card wins by $35 per year, plus you get the free checked bag perk.

Frequently Asked Questions

Can I hold multiple United cards at the same time?

Yes. Some people hold both the Gateway card (for everyday spending) and the Explorer card (for travel and dining). Chase's rules allow you to hold multiple cards in the same product family, though you should space applications at least 30 days apart to avoid triggering fraud detection.

Do United miles expire?

Miles do not expire as long as you have account activity at least once every 24 months. Activity includes earning miles, redeeming miles, or even just logging into your account. If your account goes inactive for 24 months, United will close it and you lose the miles.

What is the difference between the personal and business United cards?

The rewards rates and perks are identical between the personal and business versions of each card. The main difference is that business cards report to business credit bureaus, not personal credit bureaus, and you can earn miles on business expenses. Choose the business version only if you have a registered business and want to separate business and personal spending.

Is the $100 United travel credit worth the full $100?

Yes, if you use it. The credit applies to any United purchase: flights, seat upgrades, baggage fees, or even United gift cards. The catch is that it resets on January 1 each year, so you must use it or lose it. If you book at least one United flight per year, you can almost always find a use for the credit.

How do I know what my miles are worth when I redeem them?

The value depends on what you book. Redeeming miles for a domestic flight might be worth 1 to 1.5 cents per mile. Redeeming for an international business class flight might be worth 3 to 5 cents per mile. The best way to check is to search for a flight on United's website, note the cash price, then see how many miles it costs, and divide the price by the miles to get your cents-per-mile value.
