What the United Airlines card sign-up bonus actually gives you

The United Airlines credit card offers a sign-up bonus in the form of miles — the currency you use to book flights or other travel rewards through United's program. The exact number of miles varies by which United card you choose and changes periodically, but recent offers have ranged from 50,000 to 120,000 miles. You earn these miles by spending a set amount on the card within a specific timeframe, usually three to six months.

The miles themselves have real value, but not a fixed dollar amount. A mile might be worth roughly 1 cent when you redeem it for a flight, though that varies wildly depending on the route, the time of year, and how many miles the flight costs. A 50,000-mile bonus could cover a domestic round trip on a slow travel day, or it might cover only a one-way flight during peak season. You cannot convert miles to cash directly, and you cannot transfer them to another person's account — they stay in your United account until you use them.

Key Takeaways

  • United offers several credit cards with different sign-up bonuses, ranging from 50,000 to 120,000 miles depending on the card tier and current promotion.
  • You earn the bonus by spending a required amount — typically $3,000 to $5,000 — within three to six months of opening the account.
  • The card charges an annual fee that ranges from $0 to $450 depending on which United card you choose, and this fee recurs every year you keep the card open.
  • Miles expire if your United account sits inactive for 18 months, so you need to use or earn miles regularly to keep them from disappearing.
  • The real value of the bonus depends on when and where you want to fly, because peak-season flights cost far more miles than off-season ones on the same route.

Which United card offers what bonus

United issues four main credit cards through Chase, each with a different sign-up bonus and annual fee. The United Gateway card (no annual fee) offers a smaller bonus, usually 30,000 to 40,000 miles. The United Explorer Card ($0 first year, then $95) typically offers 50,000 to 60,000 miles. The United Explorer Card Prime ($0 first year, then $95) offers similar bonuses. The United Club Infinite Card ($550 annual fee) offers the largest bonus, often 120,000 miles or more, plus lounge access and other perks.

The bonus amount and the spending requirement both shift based on what United and Chase are promoting at any given time. Before you open an account, check the current offer on Chase's website or United's website directly — the bonus you see advertised elsewhere may have changed. The spending requirement is usually $3,000 to $5,000 within three months, though premium cards sometimes require $5,000 to $7,000.

How to earn the bonus and what happens next

After you open the card and it arrives, you have a set window — typically three to six months — to spend the required amount. Every purchase on the card counts toward that spending requirement, including groceries, gas, and bills. Once you hit the threshold, the miles post to your United account automatically, usually within one to two billing cycles. You do not need to do anything to trigger the miles; they arrive on their own schedule.

After the bonus posts, you can use the miles when ready to book flights through United's website or app. You can also hold them in your account for later, though remember that miles expire if your account has no activity for 18 months. Activity includes earning or redeeming miles, so even a small purchase on the card or a single mile earned from a flight keeps the clock reset.

Annual fees and whether the card pays for itself

Three of the four United cards charge an annual fee after the first year. The Gateway card has no annual fee. The Explorer Card and Explorer Card Prime both charge $95 per year. The Club Infinite Card charges $550 per year but includes $100 in United travel credits and lounge access, which can offset some of the cost if you use them.

Whether the card "pays for itself" depends on how much you fly and how much you spend on the card outside of the sign-up bonus. If you fly United once or twice a year and spend little on the card otherwise, the annual fee may outweigh the value you get. If you fly frequently or use the card for everyday spending and earn miles on top of the sign-up bonus, the fee becomes easier to justify. Calculate this for your own situation: add up the miles you expect to earn in a year from regular spending, estimate their value based on flights you actually take, and compare that to the annual fee.

How miles actually work when you book a flight

When you log into your United account and search for flights, you can filter results to show "award availability" — flights you can book with miles instead of cash. The number of miles required for the same route varies dramatically by season, day of the week, and how far in advance you book. A flight that costs 25,000 miles in January might cost 50,000 miles in July on the same route.

You can also use miles to upgrade a paid ticket to a higher cabin, or to cover baggage fees and other charges, though these uses typically give you less value per mile than booking a full flight. Some people transfer miles to United's partner airlines, which can sometimes stretch the value further, but that requires research and planning.

What to watch for before you explore

Check whether you have opened a United credit card in the past 24 months. Chase has a rule called the "24-month rule" that prevents you from earning a sign-up bonus on the same card more than once every two years. If you have opened a United card recently, you may not be able to earn another bonus yet, even if you close the old card.

Also verify that you can actually meet the spending requirement within the timeframe. If you cannot spend $3,000 to $5,000 on the card in three to six months through normal purchases, manufactured spending, or paying bills with the card, you will not earn the bonus. Do not open the card counting on the bonus if you cannot realistically hit that threshold.

Frequently Asked Questions

Can I use the sign-up bonus miles right away, or do I have to wait?

You can use the miles as soon as they post to your account, which is usually one to two billing cycles after you hit the spending requirement. You do not have to wait any longer. Book your flight when ready if you know when you want to travel, because award availability can change and peak-season flights fill up quickly.

What happens to my miles if I close the card?

Closing the card does not automatically cancel your miles. The miles stay in your United account as long as your account remains active — meaning you earn or redeem miles at least once every 18 months. If your United account goes inactive for 18 months, the miles expire. You can keep the account active by earning miles from flights, partner purchases, or even small credit card transactions.

Is the sign-up bonus worth the annual fee?

That depends on your flying habits and spending. If you fly United at least once or twice a year and use the card for regular purchases, the miles you earn beyond the bonus often cover the annual fee. If you rarely fly or do not use the card much, the fee may not be worth it. Calculate your expected annual miles from regular spending and compare that value to the fee.

Can I get the bonus if I already have a United card from a different bank?

The 24-month rule applies only to the same card from Chase. If you have a United card from a different issuer or an older Chase United card, you may still be able to earn a bonus on a different United card. Check Chase's current terms, as these rules can change.

Do I have to fly United to use the miles, or can I book other airlines?

You can book flights on United's partner airlines using your miles, including airlines like Air Canada, Lufthansa, and others in the Star Alliance network. Partner bookings sometimes require more miles than United flights on the same route, but they give you more options if United does not fly where you want to go.
