Do Delta Miles Expire?

Delta SkyMiles don’t expire regardless of the activity in your account. Your Delta SkyMiles won’t disappear because you didn’t earn more within a specific time frame. That means you don’t have to come up with creative ways to get miles in a pinch just to keep them alive.

In contrast, many frequent flyer programs have expiration policies usually ranging from 18 to 36 months. So if you’re reluctant to join a loyalty program for fear of not flying often enough, remember that you can accumulate SkyMiles at a slow rate without losing them.

When can Delta close your account?

Although Delta SkyMiles don’t expire for inactivity, the airline can deactivate or close an account if the account holder:

• Has fraudulent activity on their account.

• Requests account closure.

• Dies.

• Doesn’t respond to communication regarding their account.

• Moves to a country where membership is prohibited by law.

• Violates terms of participation in the program.

Staying on Delta’s good side is important if you don’t want your account closed. Here are some of the most important rules to remember:

• Members can’t have multiple SkyMiles numbers.

• First, middle and last names must match a government-issued identification.

• Members can’t sell or barter miles or other benefits to another member.

To avoid the closure of your SkyMiles account, make sure your contact information is up to date and the name matches your ID, and log in to your account every once in a while to keep it active. Additionally, don’t exchange SkyMiles for money, or your program membership could be terminated for violation of terms.

Earn Delta miles quickly

Although you don’t need to keep earning Delta SkyMiles to extend their expiration date, it’s good to have some activity on the account to keep it in good standing.
