We are an independent publisher. Our reporters create honest, accurate, and objective content to help you make decisions. To support our work, we are paid for providing advertising services. Many, but not all, of the offers and clickable hyperlinks (such as a “Next” button) that appear on this site are from companies that compensate us. The compensation we receive and other factors, such as your location, may impact what ads and links appear on our site, and how, where, and in what order ads and links appear. While we strive to provide a wide range of offers, our site does not include information about every product or service that may be available to you. We strive to keep our information accurate and up-to-date, but some information may not be current. So, your actual offer terms from an advertiser may be different than the offer terms on this site. And the advertised offers may be subject to additional terms and conditions of the advertiser. All information is presented without any warranty or guarantee to you.

This page may include: credit card ads that we may be paid for (“advertiser listing”); and general information about credit card products (“editorial content”). Many, but not all, of the offers and clickable hyperlinks (such as a “Apply Now” button or “Learn More” button) that appear on this site are from companies that compensate us. When you click on that hyperlink or button, you may be directed to the credit card issuer’s website where you can review the terms and conditions for your selected offer. Each advertiser is responsible for the accuracy and availability of its ad offer details, but we attempt to verify those offer details. We have partnerships with advertisers such as Brex, Capital One, Chase, Citi, Wells Fargo and Discover. We also include editorial content to educate consumers about financial products and services. Some of that content may also contain ads, including links to advertisers’ sites, and we may be paid on those ads or links.

Airline frequent flyer program rules can be confusing – especially so if you collect a number of different types of miles & points. So you might be wondering: Do Delta miles expire?

The answer is no. That’s a huge bonus if you’ve been collecting miles from top Delta credit cards like the Delta SkyMiles® Gold American Express Card, Delta SkyMiles® Gold Business American Express Card or Delta SkyMiles® Platinum American Express Card. Even if you don’t have immediate travel plans, you can rest easy knowing your miles won’t vanish if you don’t use them right away.

Here’s why that sets Delta apart from other airlines.

Delta miles do not expire

To appreciate the fact that Delta miles don’t expire, we’ve got to look at competing frequent flyer programs. Losing travel rewards simply because they expired is the worst, so don’t let it happen to you.

Here’s a look at airline mileage expiration policies:

Use Delta miles for free flights

The downside of Delta’s program is that there’s no official Delta award chart. That means you’ll have to look up your particular flight to see how many miles it’ll cost. The good news is that Delta has frequent flash sales, and if you have certain Delta credit cards, you can use Delta’s Pay With Miles feature. With this option, your Delta miles are worth 1 cent each towards the cost of your ticket.

Check out our Hot Deals page for the latest and greatest Delta credit card offers. But just remember, you’ll want to apply for these cards when their welcome offers are at their highest because you can only earn the bonus on a particular Amex card once per lifetime. Delta miles value can be significant, especially if you jump on one of their many dirt-cheap Delta SkyMiles deals.

As an alternative, you could earn Amex Membership Rewards points which transfer to Delta at a 1:1 ratio with these cards:

Bottom line

Delta miles do not expire, regardless of whether or not there is any activity in your Delta frequent flyer account. That’s a unique benefit of Delta’s frequent flyer program, as a majority of other types of airline miles will expire if you don’t meet certain criteria.
