Few things are more exciting than earning credit card points, airline miles, and hotel points to fuel your travels. But accidentally letting those hard-earned miles expire? Talk about frustrating.
Every airline sets its own policies for when miles expire – and more and more have eliminated that expiration policy entirely, making your miles good for life. Still, it's confusing to keep track of when your stash of miles might lapse.
So we'll break down the policies of all the major U.S. airlines, as well as some of the biggest and best international frequent flyer programs. And we'll give you some tips on how to make sure your miles don't accidentally expire.
Delta Air Lines
If you have a stash of Delta SkyMiles, you're in luck. That's because SkyMiles will never expire. Once you earn them, they are yours to keep – regardless of whether or not you have any recent activity in your account.

But just because Delta SkyMiles don't expire doesn't mean you should hoard them in your account. As with any frequent flyer program, these miles get less valuable over time. The airline will simply charge more for the same mileage redemptions – sometimes jacking up the price overnight. Use your SkyMiles; that's what they're there for.

American Airlines AAdvantage miles will expire 18 months after you earn them unless there is some sort of activity in your account. That's right – use them or lose them in 18 months.
The easiest way to find the expiration date on your American Airlines AAdvantage account is to log in and click on the wallet option in your account. From here, you will see an expiration date under the award miles square on the left-hand side pictured below.
If the clock is ticking on your miles, don't worry. You can easily reset the 18-month clock by either earning or redeeming AAdvantage miles. That means there are plenty of ways to keep your miles from expiring.

First things first, if you hold a co-branded American Airlines credit card, making any purchase on the card will earn AAdvantage miles and reset the expiration clock on your stash of miles.
On top of that, American Airlines has both shopping and dining portals that allow you to earn miles for online shopping or for eating out at restaurants. All you have to do is link any credit card to the portals and make a purchase. There is no requirement that it is an American Airlines credit card. You will earn miles and reset the clock on your mileage expiration.
Both programs are free to use and the only requirement is that you have an American Airlines Advantage account.

Back in August 2019, United Airlines removed its expiration window for unused MileagePlus miles, joining Delta and just a handful of other airlines. Until that point, United had a similar policy to American Airlines. Now, your United MileagePlus miles will never expire.
But just as with Delta SkyMiles, just because they don't expire shouldn't be an excuse to let them pile up. As with all milage programs, they will get less valuable over time as the airlines are constantly changing redemption rates for using your miles. And when they do, that's almost never good news.
Southwest Airlines is one of the most lenient airlines in the industry when it comes to fees and just about everything else airlines nickel and dime you for. In our opinion, it is what sets Southwest apart and makes them unique.
As of October 2019, Southwest Rapid Rewards points no longer expire. Until that point, Southwest Rapid Rewards points expired after 24 months of inactivity.
Alaska Mileage Plan miles will expire after 24 months of no account activity. Just like other programs whose miles expire, keeping your miles alive shouldn't be terribly difficult.
If you hold a co-branded Airlines Airlines credit card, making any purchase on the card will earn Mileage Plan miles and reset the expiration clock on your stash of miles.
Like most other airlines, Alaska Airlines has both a shopping and dining portal which makes it possible to earn additional miles for online shopping or for eating out at restaurants. All you have to do is link any credit card to the portals and make a purchase. Once again, there is no requirement that it is an Alaska Airlines credit card. Your purchase will earn miles and reset the clock on your mileage expiration.
Both programs are free to use and the only requirement is that you have an Airlines Airlines Mileage Plan account.

If you have a stash of jetBlue True Blue miles, they're safe. As of May 2019, True Blue miles do not expire. Prior to May 2019, TrueBlue points expired every 12 months if there was no activity on the account.
