American Airlines transfer partners let you move your AAdvantage miles to airline and hotel programs, sometimes at a better redemption rate than booking directly with American.

American Airlines does not transfer miles to other airlines the way some competitors do. Instead, American offers partnerships with specific hotel chains and a smaller set of airlines where you can move your miles in fixed increments. The transfer rate is usually one AAdvantage mile equals one point in the partner program, though some hotel partners offer bonus conversions during promotional periods.

The real value comes from understanding which partners give you more purchasing power per mile than American's own award chart. A hotel night that costs 50,000 American miles might cost only 40,000 points in that hotel's own program, meaning a transfer saves you 10,000 miles. The catch: you have to move miles in chunks (usually 1,000 at a time, with a 1,000-mile minimum), and once transferred, those miles cannot come back.

Key Takeaways

  • American Airlines transfers miles to roughly a dozen hotel chains and a handful of airlines, with transfers processed in 24 to 48 hours.
  • Hotel transfers often provide better value than American's direct redemptions, especially for luxury properties where nightly rates are high.
  • Airline transfers are useful mainly for partners where American award availability is limited or where partner airlines offer cheaper awards on routes American does not serve.
  • Transfers happen in 1,000-mile increments with a 1,000-mile minimum, and miles cannot be transferred back once moved.
  • Some hotel partners run periodic bonus conversion promotions where your miles are worth more when transferred during a specific window.

Hotel Transfer Partners and When They Make Sense

American's hotel partners include Marriott Bonvoy, Hilton Honors, World of Hyatt, IHG One Rewards, Wyndham Rewards, and Accor Live Limitless. The standard conversion is one AAdvantage mile to one point in the partner program. You transfer in 1,000-mile blocks, and the miles land in your hotel account within 24 to 48 hours.

A transfer makes sense when the hotel's award chart is cheaper than American's. For example, a Marriott Bonvoy category 7 property might cost 50,000 Bonvoy points per night, while American's award chart prices the same hotel at 60,000 miles. By transferring 50,000 miles to Marriott, you save 10,000 miles and get the same night. This advantage is largest at luxury properties, where nightly point costs are high and American's fixed-tier pricing does not reward you for choosing expensive hotels.

Marriott Bonvoy and Hilton Honors are the most useful because they have the largest property networks and the most transparent award charts. World of Hyatt and IHG One Rewards work well if you stay at those chains regularly. Wyndham and Accor are smaller networks and generally less valuable unless you have a specific property in mind.

Airline Transfer Partners and Limited Availability

American transfers miles to Alaska Airlines, British Airways Executive Club, Etihad Guest, and a few others, though the list is smaller than hotel partners. The one-to-one conversion applies here as well. Airline transfers are less commonly valuable because American's own award chart is competitive on most routes, and partner airlines often have higher award prices than American.

An airline transfer makes sense in two situations. First, when American has no award availability on a route you need but a partner airline does. For example, if American has no business-class seats to London but British Airways does, transferring to BA Executive Club might be your only option. Second, when a partner airline's award chart is genuinely cheaper. This is rare but does happen on certain regional or international routes.

Alaska Airlines is the most practical partner because it serves many routes American does not and has a straightforward award chart. British Airways is useful for transatlantic business-class awards. Etihad Guest can offer value on Middle East routes, but availability is limited and the program is less transparent than American's.

How to Transfer Miles and What Happens Next

You initiate a transfer through your AAdvantage account online. Log in, find the "Transfer Miles" or "Manage Miles" section, select your partner program, and enter the number of miles you want to move in 1,000-mile increments. You will see the partner account number field — make sure you enter this correctly, because transfers cannot be reversed if the number is wrong.

The transfer processes within 24 to 48 hours. You will receive a confirmation email from American and a separate email from the partner program showing the points have arrived. From that point, the miles are in the partner program and subject to that program's rules, not American's. If you change your mind, you cannot transfer them back to American.

Some transfers trigger a small fee, though most hotel and airline transfers are free. Check the transfer page before confirming to see if your chosen partner charges. The fee is usually $5 to $10 per transfer, not per mile.

Bonus Conversion Promotions and Timing

Hotel partners periodically run bonus conversion offers where your miles are worth more during a limited window. For example, Marriott Bonvoy might offer a 30% bonus, meaning 10,000 AAdvantage miles become 13,000 Bonvoy points instead of 10,000. These promotions typically last one to four weeks and are announced via email to AAdvantage members and on partner websites.

Bonus promotions are worth watching for if you are planning a hotel transfer anyway. A 30% bonus can swing the math in favor of a transfer that would otherwise be neutral. However, do not transfer miles just because a bonus exists — only transfer if the partner program offers better value than American's direct redemption for the specific property you want to book.

You can sign up for email alerts from hotel partners to be notified when bonuses are announced. American also lists active promotions in the "Transfer Miles" section of your account, though the list is not always complete.

Comparing Transfer Value to Direct Redemption

Before you transfer, compare the cost in both programs. Look up the specific property or flight on both American's award chart and the partner program's chart. Calculate the miles per night or per ticket in each program, then decide which is cheaper.

For hotels, use the partner program's website to search your dates and property. Note the nightly point cost. Then check American's award chart to see what tier that property falls into and how many miles American charges. If the partner is cheaper, a transfer makes sense. If American is cheaper or equal, do not transfer.

For airlines, the math is trickier because partner airlines often have dynamic pricing or fuel surcharges that American does not. Search the partner airline's website for your route and dates, note the award cost, then compare to American's fixed award chart. Partner airlines are rarely cheaper, so transfers are usually a last resort when American has no availability.

What Happens to Transferred Miles if You Do Not Use Them

Once miles land in a partner program, they are subject to that program's expiration and forfeiture rules, not American's. Most hotel programs do not expire points as long as you have account activity at least once every 24 months. Activity includes earning, redeeming, or even just logging in to your account. Airline programs vary — some expire points after 18 months of inactivity, others after three years.

If you transfer miles to a partner and then do not use them, you risk losing them if the partner program's inactivity rules kick in. Before you transfer, make sure you have a realistic plan to use those points within the partner program's activity window. If you are unsure whether you will book with that partner, do not transfer.

Frequently Asked Questions

Can I transfer miles back to American if I change my mind?

No. Once miles are transferred to a partner program, they cannot be moved back to American. This is why it is important to confirm your partner account number is correct before you initiate the transfer. If you enter the wrong account number, contact American customer service when ready — they may be able to reverse a transfer within a short window, but this is not may provide.

Do I have to transfer in 1,000-mile blocks?

Yes. American requires transfers in 1,000-mile increments with a 1,000-mile minimum. You cannot transfer 500 miles or 1,500 miles. If you want to move 2,500 miles, you would transfer 2,000 and then 500 in separate transactions, or transfer 3,000 if you have them available.

Which transfer partner gives the best value?

It depends on where you want to stay or travel. Marriott Bonvoy and Hilton Honors offer the most consistent value for hotel stays because they have large networks and transparent award charts. For airlines, value is rare — transfers are usually a backup when American has no availability. Check the specific property or route you want before deciding.

How long does a transfer take?

Most transfers process within 24 to 48 hours. You will receive confirmation emails from both American and the partner program. In rare cases, transfers can take up to five business days, especially if there is a system issue or if you transfer during a weekend.

Are there any fees for transferring miles?

Most transfers are free, but some partners charge a small fee, typically $5 to $10 per transfer. Check the transfer page in your AAdvantage account before you confirm — it will show any applicable fees for your chosen partner.
