Yes, AAdvantage miles expire, but only when your account sits idle. As reported, American expires miles after 24 months without qualifying activity, and any one qualifying activity resets the expiration date to 24 months from that activity. American's own pages refused to load for our check on October 19, 2026, so this guide gives the rule and the reinstatement details as reported and marks what we couldn't confirm.
If your miles have already lapsed, American can bring them back for a fee. The window is 24 months, as reported, and the price isn't one you should guess, so get a quote first.
The 24-Month Rule
Your AAdvantage miles expire 24 months after your last qualifying activity. Earning or redeeming miles on American or with an AAdvantage partner at least once in that stretch extends the expiration date 24 months from the date of the activity.
As reported, these count:
- Flying on American or a partner airline and crediting the flight to your AAdvantage number.
- Spending at an AAdvantage Dining partner.
- Crediting a hotel stay to AAdvantage and earning miles.
- Spending miles.
That list matters because the cheapest fix is the one you do before the date. A single dining purchase or a hotel stay credited to your account is enough to keep the whole balance alive for another two years.
Who Doesn't Have to Worry
Members under 21 are reported to be exempt. So are primary holders of an American co-branded credit card, as long as the card stays open. Each report limits the exemption to the primary cardholder.
Our list of airline credit cards with miles that never expire covers the big U.S. programs that dropped expiration, with American as the exception.
Reinstating Expired Miles
As reported, you can reinstate miles that expired within the last 24 months, online or by phone.
The price depends on how many miles you restore. We couldn't read a fee table on American's site, and the figures that circulate come from 2022 quotes: $60 for 5,000 miles, $100 for 10,000 and $700 for 100,000. That works out to roughly 0.7 to 1.2 cents a mile. American may have changed its pricing since, so treat those as the shape of the cost and ask for today's number.
When Reinstating Is Worth It
Start with what you'd do with the miles. If you have a specific award in mind and the quote is near a cent a mile, reinstating can make sense, because you're buying back a balance that would otherwise be gone. If you don't, the same money buys little.
The order that costs least:
- Check your expiration date in your AAdvantage account.
- If it's close, do a qualifying activity before it passes.
- If the miles already expired, ask American for a reinstatement quote and compare it to what a replacement award would cost.
Don't pay for reinstatement before you've seen the price in writing.
