Where your United miles come from and how to see them

When you use a United-branded credit card, the card issuer (usually Chase) deposits miles into your United MileagePlus account automatically. You do not have to do anything to "claim" them — they appear in your account within one to three business days after a purchase posts to your card. The miles show up under your MileagePlus number, which is printed on your card and also visible when you log into your United account online.

To see your miles balance at any time, log into MileagePlus.com with your account username and password, or read the United app. Your current balance appears on the dashboard when ready. If you have made a recent purchase and the miles have not yet shown up, check back in a few days — the delay is normal and does not mean anything went wrong.

Some cards also offer bonus miles when you first open the account (often called a sign-up bonus) or when you hit a spending threshold in the first few months. These bonus miles follow the same timeline: they post automatically once the condition is met, usually within one to three business days.

Key Takeaways

  • Miles from your United credit card post automatically to your MileagePlus account within one to three business days after a purchase clears.
  • You can check your balance anytime by logging into MileagePlus.com or the United app with your account credentials.
  • Sign-up bonuses and spending bonuses post automatically once the requirement is met, with no extra step needed on your part.
  • If miles do not appear after three business days, contact United customer service or your card issuer to investigate the delay.
  • Miles expire if your account is inactive for 24 months, so use or transfer them periodically if you do not fly often.

Why miles might not show up right away

The most common reason miles take time to appear is that your purchase has not yet posted to your card. When you swipe your card, the transaction is "pending" for a day or two. Miles do not deposit until the transaction actually posts — that is, until the merchant has sent the final charge to your card issuer. Once it posts, miles usually follow within 24 hours.

A second reason is that the purchase did not may have access to for miles. United cards earn miles on most everyday purchases, but some transactions do not count: balance transfers, cash advances, wire transfers, and purchases made outside the United States sometimes earn zero miles or reduced miles. Check your card's terms to see which categories earn at full rate.

If you bought a United ticket directly from United.com or at the airport, the miles should post automatically. If you bought through a third-party site like Expedia or Kayak, the miles may take longer or may not post at all — those sites do not always report the purchase back to United in a way that triggers the miles credit. For airline tickets, buying directly from United ensures the miles post.

Checking your miles history and transaction details

Log into your MileagePlus account and select "Account" or "My Account," then look for "Activity" or "Transaction History." This page shows every deposit and withdrawal of miles, with dates and amounts. You can usually filter by date range to find a specific transaction.

If you see a purchase on your credit card statement but no corresponding miles in your MileagePlus history, write down the transaction date, merchant name, and amount. Then contact United customer service with those details. They can search their records to see whether the miles were posted under a different date or whether the merchant failed to report the purchase. United can often manually add missing miles if the transaction genuinely may have access to.

Keep in mind that some card issuers (like Chase) also show your miles balance in your online banking portal, separate from MileagePlus.com. The two should always match, but if they do not, the MileagePlus.com balance is the official one — that is what United uses when you book a flight.

Bonus miles and how they post

Most United credit cards offer a sign-up bonus: a lump sum of miles (often 50,000 to 100,000) if you spend a certain amount in the first three months. This bonus posts automatically once you meet the spending requirement. You do not need to request it or submit proof of spending — the card issuer tracks your purchases and deposits the bonus when the threshold is crossed.

Some cards also offer annual bonuses: a smaller number of miles (often 10,000 to 15,000) that post automatically on your card anniversary each year, just for keeping the card open. These post on the same date each year and require no action from you.

Bonus miles post to the same MileagePlus account linked to your card. If you have multiple United cards or multiple MileagePlus accounts, make sure you are checking the right account. You can link only one MileagePlus number to each credit card, so all miles from that card go to that one account.

What to do if miles are missing or delayed

Wait three business days after a purchase posts to your card. If the miles still have not appeared, gather the following information: the transaction date, the merchant name, the purchase amount, and your MileagePlus account number. Then contact United customer service by phone, chat, or the MileagePlus website.

United can see whether the merchant reported the purchase to them. If the merchant did report it but the miles did not post, United can usually add them manually. If the merchant did not report it (which sometimes happens with third-party booking sites), United may not be able to help, but it is worth asking.

If you believe the delay is on your card issuer's side (for example, if the transaction posted to your card but miles did not appear after three days), contact your card issuer's customer service line. They can escalate the issue to the rewards department and investigate whether the transaction was reported to United correctly.

Miles expiration and keeping your account active

United miles expire if your MileagePlus account has no activity for 24 consecutive months. Activity includes earning miles, redeeming miles, or even just logging into your account. If you do not fly often or do not use your United card regularly, set a phone reminder to log into MileagePlus at least once every 23 months to keep your account active.

If your miles do expire, you can sometimes reactivate your account and restore the miles by paying a fee (usually $25 to $50) and completing a may have access to activity, such as a flight or a credit card purchase. However, it is much easier to prevent expiration by staying active.

If you have a United credit card, using it for any purchase — even a small one — counts as activity and resets the 24-month clock. So regular card use keeps both your miles and your account safe.

Transferring miles to another person or account

You can transfer miles from your MileagePlus account to another person's account, but there are rules. You can transfer to a family member or friend, but United charges a fee (usually $12.50 per 1,000 miles transferred). The recipient must have an active MileagePlus account, and you must both be at least 18 years old.

To transfer, log into your MileagePlus account, find the "Transfer Miles" option, and enter the recipient's MileagePlus number and the number of miles you want to send. The transfer usually completes within one business day.

You cannot transfer miles to a different account in your own name — miles are tied to a single MileagePlus account. If you have opened a new MileagePlus account by mistake, contact United to request a merge of the two accounts before the old one expires.

Frequently Asked Questions

How long does it take for miles to show up after I use my United card?

Miles usually post within one to three business days after your purchase posts to your card. The purchase itself may take one to two days to post, so the total time from swipe to miles in your account is typically two to four business days. If it has been longer than that, contact United or your card issuer.

Do I earn miles on my credit card bill payment?

No. Paying your credit card bill does not earn miles. Only purchases made with the card earn miles. Balance transfers and cash advances also do not earn miles on most United cards.

What happens if I close my United credit card?

Closing the card does not delete your miles or your MileagePlus account. Your miles stay in your MileagePlus account indefinitely, as long as your account remains active (you log in or earn miles at least once every 24 months). You can still use those miles to book flights even after you close the card.

Can I combine miles from two different MileagePlus accounts?

United does not allow you to merge active accounts, but you can transfer miles from one account to another for a fee. If you have duplicate accounts that are both inactive, contact United to request a merge before the miles expire.

Why did my sign-up bonus not post?

The most common reason is that you have not yet met the spending requirement. Check your card agreement for the exact amount you need to spend and the timeframe (usually three months). If you have met it and the bonus has not posted after three business days, contact your card issuer to verify that your spending was tracked correctly.
