Most big US airlines have stopped expiring their miles. Delta, United, Southwest, JetBlue and Alaska miles now sit in your account for as long as you like. American Airlines is the exception. If you don’t earn or redeem any AAdvantage miles for 24 months, your whole balance can disappear in one go.
The good news: keeping American miles alive is easy once you know the rules. One small transaction every two years is enough, and some members don’t have to do anything at all. This guide explains how the expiration rule works, who is exempt, the simplest ways to reset the clock, and what to do if your miles have already expired.
Do American Airlines miles expire?
Yes. Under the AAdvantage terms, all the miles in your account expire if there is no “qualifying activity” for 24 months in a row. Qualifying activity simply means earning miles or redeeming miles, either with American or with one of its AAdvantage partners.
Each time you earn or redeem, American pushes your expiration date out to 24 months from the date of that activity. So if your last activity is on October 6, 2026, your miles are safe until October 6, 2028. If you add one more mile before then, the clock starts again.
Two details matter here:
- It’s all or nothing. One qualifying activity protects your entire balance, not just the miles you earned that day. You don’t need to spend or earn thousands of miles.
- The rule is rolling. There is no fixed yearly deadline. Your date depends only on your last activity.
You can see your exact date by logging in to your AAdvantage account. Your balance appears at the top, with the earliest date your miles could expire.
Who is exempt from the 24-month rule?
Some members don’t need to worry about expiration at all.
AAdvantage credit card holders
If you are the primary cardmember on an AAdvantage co-branded credit card, your miles won’t expire for as long as that card account stays open. This applies to the primary cardholder, not authorized users.
In 2026, Citi became the only US issuer of AAdvantage credit cards. Barclays AAdvantage cardholders were moved to comparable Citi cards from April 2026. If you were part of that switch, it’s worth checking that your new Citi card is linked to the right AAdvantage number.
If you close your AAdvantage card, the protection doesn’t vanish overnight. You’ll need qualifying activity either within four months of closing the card or within 24 months of your last activity, whichever date is later.
Members under 21
AAdvantage members under 21 are not subject to the 24-month rule. Your profile needs a valid birth date for this to apply. Once you turn 21, you’ll need earning or redeeming activity within 24 months of your 21st birthday to keep your miles.
9 easy ways to keep American miles from expiring
If you’re not exempt, any of these will reset your 24-month clock. Pick whichever fits your normal spending, so you don’t buy anything you wouldn’t buy anyway.
1. Shop through AAdvantage eShopping
AAdvantage eShopping is American’s online shopping portal. You click through the portal to a retailer you already use, shop as normal, and earn miles on the purchase. Even a small order can post miles and reset your expiration date. Allow a few weeks for the miles to show up, so don’t leave this until the last minute.
2. Join AAdvantage Dining
Register a debit or credit card with AAdvantage Dining, then eat at participating restaurants. Miles post automatically after you pay with the registered card. It’s a “set it and forget it” option that can quietly keep your account active.
3. Use SimplyMiles offers
SimplyMiles lets you link an eligible card and activate offers from brands you already shop with. Each completed offer earns AAdvantage miles, which counts as activity.
4. Transfer Citi ThankYou points
Since July 2025, Citi ThankYou points can be transferred to AAdvantage. Premium cards such as the Citi Strata Premier and Citi Strata Elite transfer at 1:1, so 1,000 points become 1,000 miles. No-annual-fee ThankYou cards transfer at a weaker rate of about 1,000 points to 700 miles. Transfers are usually instant, which makes this one of the fastest ways to save miles that are about to expire.
Note that Chase Ultimate Rewards, Amex Membership Rewards and Capital One miles do not transfer to AAdvantage.
5. Convert hotel points
Some hotel programs, including Marriott Bonvoy, convert points into AAdvantage miles. The ratio is weak (Marriott converts at 3 points to 1 mile), so this is usually a last resort. But if you have a few thousand spare hotel points, converting a small amount is enough to reset the clock.
6. Fly American or a oneworld partner
Any paid flight on American or an eligible oneworld partner that earns AAdvantage miles counts. Just make sure your AAdvantage number is on the booking.
7. Book hotels and car rentals with AAdvantage partners
Many hotel and car rental brands let you earn AAdvantage miles instead of their own points. Booking a single night or a short rental this way counts as earning activity.
8. Redeem a small award
Redeeming miles also resets the clock. If you have a trip coming up, book an award flight. Domestic one-way awards on American can start from 7,500 miles. This keeps your remaining balance alive and covers a flight you’d take anyway.
9. Use an AAdvantage credit card
Spending on an AAdvantage card earns miles, and as the primary cardholder you’re exempt from expiration while the card is open. If you already want an airline card, this is the most hands-off solution.
What to do if your American miles have expired
If your miles have already expired, they’re not necessarily gone for good. American lets you reactivate up to 500,000 expired miles, as long as you request it within 24 months of the expiration date. There is a fee, and it’s based on how many miles you reactivate. You only get one transaction to do it, so reactivate the full amount you need at once.
Before paying, compare the fee with the value of the miles. AAdvantage miles are commonly valued at around 1.2 to 1.4 cents each, so reactivating a large balance is often worth it. Reactivating a small balance may not be.
Also note that earning new miles after your balance expires does not bring the old miles back. It only starts a new balance.
Common mistakes that cause miles to expire
Most people who lose AAdvantage miles don’t do it on purpose. They simply forget, or they assume something counts as activity when it doesn’t. Watch out for these common mistakes:
- Thinking an authorized user card protects you. Only the primary cardmember on an AAdvantage credit card is exempt from expiration. If you’re an authorized user on someone else’s card, you still need your own qualifying activity.
- Waiting until the last week. Miles from shopping portals and dining programs can take several weeks to post. Your activity date is the date the miles are credited, so start early.
- Forgetting about a closed card. Once you close your AAdvantage card, the exemption ends. Make a note of your new deadline straight away.
- Leaving out your AAdvantage number. If your number isn’t on a flight, hotel or car booking, you won’t earn miles, and nothing will reset your clock.
Tips to never lose miles again
- Set a calendar reminder 20 months after your last activity. That gives you four months to earn or redeem something.
- Use a points tracking app. Many apps show all your loyalty balances and expiration dates in one place.
- Keep your birth date and email up to date in your AAdvantage profile, so you get American’s reminder emails.
- Check your account after big changes, such as closing a credit card or switching from Barclays to Citi.

Conclusion
Keeping American miles from expiring takes very little effort. Earn or redeem at least once every 24 months, or hold an AAdvantage credit card as the primary cardmember. A quick eShopping order, a dining transaction or a small Citi points transfer is all it takes. Check your expiration date today, set a reminder, and your miles will be there when you’re ready to use them.
