Yes, you can transfer Amex points to United, but only through specific Amex cards and with some limits on value

American Express lets you move points from certain Amex cards directly to United Airlines' MileagePlus program. The transfer happens when ready, and United will add those miles to your account right away. However, not every Amex card offers this option, and the conversion rate is fixed at 1 Amex point = 1 United mile — meaning you don't gain or lose value in the exchange itself.

The main catch is that Amex points are often worth more when you use them for other things, like statement credits or transfers to hotel programs. Before you move points to United, it's worth checking whether you'd get better value another way.

Key Takeaways

  • Only Amex cards in the Membership Rewards program can transfer points to United; not all Amex cards have this feature.
  • Transfers happen when ready and convert at a 1-to-1 rate with no fees, but you cannot reverse a transfer once it's sent.
  • You need an active MileagePlus account with United before you can receive the transfer.
  • Amex points typically give you better value through statement credits or hotel transfers than through airline transfers, so compare your options first.

Which Amex cards let you transfer to United

The Amex cards that offer Membership Rewards points can transfer to United. This includes cards like the Amex Platinum Card, Amex Gold Card, and Amex Business Platinum Card. However, some Amex cards — like certain co-branded cards or older products — do not participate in the transfer program at all.

The easiest way to check is to log into your Amex account online or through the mobile app. Go to the rewards section and look for "Transfer Points" or "Airline Transfers." If you see United listed as an option, your card supports it. If the option doesn't appear, that card cannot transfer to United.

How to transfer your points to United

Log into your American Express account and navigate to the rewards or points section. Look for the option to transfer points — this is usually labeled "Transfer Points," "Move Points," or "Send Points to Partners." Select United Airlines from the list of transfer partners.

Enter the number of points you want to transfer. Amex will show you the equivalent number of United miles you'll receive (it's a 1-to-1 conversion). You'll also need to provide your United MileagePlus account number so Amex knows where to send the miles. Double-check this number — if you enter it wrong, the miles go to the wrong account and cannot be recovered.

Review the transfer details and confirm. The miles typically appear in your United account within a few hours, though Amex says it can take up to 24 hours. There is no fee to transfer.

What you need before you transfer

You must have an active United MileagePlus account. If you don't have one, you can open it for free on United's website — it takes about five minutes. You'll need your MileagePlus number before you start the transfer from Amex, so have it ready.

There is no minimum or maximum number of points you can transfer in a single transaction, though some cards may have daily or monthly limits. Check your Amex account for any restrictions specific to your card.

Why Amex points might be worth more elsewhere

Amex Membership Rewards points are flexible, and airline transfers are just one option. Many people find better value by using points for statement credits (where 1 point = 1 cent of credit), or by transferring to hotel programs like Hilton or Marriott, where the conversion rate and redemption value can be higher than airline transfers.

Before you transfer to United, think about what you actually need. If you're booking a specific United flight and have calculated that your points will cover it, transfer away. But if you're just looking to move points somewhere, spend a few minutes comparing what 10,000 points could get you as a statement credit versus as United miles.

What happens after the transfer

Once the miles land in your United account, they're yours to use. You can book flights, upgrade existing reservations, or hold them for later. United miles don't expire as long as you have some account activity at least once every 18 months — even a small purchase counts.

One important note: Amex cannot reverse a transfer once it's sent. If you transfer points by mistake or change your mind, Amex will not pull them back from United. Contact United directly to see if they can help, but there's no may provide. This is why it's critical to double-check your MileagePlus account number before you confirm.

Do I lose value when I transfer Amex points to United?
