Do Delta SkyMiles Reset Every Year?

If you collect Delta SkyMiles, it is easy to wonder whether your balance starts over when a new year begins. The short answer is no—your regular Delta SkyMiles do not reset or expire simply because the calendar year changes.

However, Delta uses several different types of balances and qualification periods, and they do not all work the same way. Your redeemable SkyMiles can remain in your account, while Medallion Qualification Dollars (MQDs) are tied to an annual qualification cycle and reset.

Understanding this difference can help you avoid confusing your regular mileage balance with your progress toward Delta Medallion Status.

Do Delta SkyMiles Reset Every Year?

No. Regular Delta SkyMiles do not automatically reset at the end of the year. Delta's SkyMiles program rules state that miles do not expire under the standard mileage expiration policy.

For example, if you finish one calendar year with 40,000 SkyMiles and do not redeem any of them, you do not normally lose those 40,000 miles simply because January 1 arrives.

Your SkyMiles balance can therefore carry forward from one year to the next.

What Happens to SkyMiles at the End of the Year?

Your redeemable SkyMiles generally remain available after December 31.

The important distinction is between:

• SkyMiles: Redeemable miles used for eligible rewards and travel.

• MQDs: A qualification metric used toward Medallion Status.

• Medallion Status: Delta's elite-status program, which operates on an annual qualification structure.

These terms are sometimes used together, but they represent different parts of the program.

What Is Delta SkyMiles Expiration?

The Delta SkyMiles expiration policy is different from many traditional airline loyalty programs. Delta's published mileage policy says that SkyMiles do not expire.

That means you generally do not need to make a qualifying transaction every few months simply to prevent your accumulated SkyMiles from disappearing.

However, Delta can deactivate or close an account in certain circumstances, including fraudulent activity, a member-requested account closure, death, or failure to respond to repeated communications concerning the account.

Do Delta Medallion Miles or MQDs Reset?

This is where the annual reset comes into play.

MQDs do not roll over from year to year. Delta states that the MQD balance resets to zero on or around January 1 each calendar year.

So, if you earned MQDs during one qualification year, those dollars cannot simply be carried into the next qualification year to help you meet the following year's requirement.

Why Do MQDs Reset?

MQDs are used to determine eligibility for Medallion Status, rather than being a spendable mileage balance.

Delta describes a Qualification Year as running from January 1 through December 31. Activity during that period is used to determine qualification for the subsequent Medallion Year. 

For example:

• You earn MQDs during 2026.

• Your 2026 activity is used to determine your qualification for the applicable subsequent Medallion Status year.

• When the next qualification year begins, the MQD counter starts again.

• Your previously earned redeemable SkyMiles are not automatically erased because of this reset.

This is why seeing an MQD balance reset does not mean your entire SkyMiles account has been reset.

SkyMiles vs. MQDs: What's the Difference?

The easiest way to understand the system is to separate the two.

FeatureDelta SkyMilesMQDs

Main purposeRedeemable loyalty milesMedallion Status qualification

Reset every January?NoYes

Roll over to the next year?Regular miles remainMQDs do not roll over

Used for award travel?Yes, subject to applicable rulesNo

Connected to Medallion qualification?Not directly in the same wayYes

This distinction is particularly important if you check your Delta account around the beginning of a new year and notice that one balance has changed while your SkyMiles remain intact.

Does Medallion Status Reset Every Year?

Medallion Status is also different from your regular SkyMiles balance.

Delta calculates Medallion Status based on activity during a Qualification Year. The current published rules identify January 1 through December 31 as the Qualification Year.

That means travelers generally need to qualify again for future Medallion Status based on the applicable requirements.

Your previous year's elite status does not mean your qualification activity continues accumulating indefinitely.

What About Existing Medallion Benefits?

Medallion benefits operate according to the applicable Medallion Year rather than simply following the lifetime balance of your SkyMiles.

For example, Delta describes its Medallion benefits as applying during the applicable Medallion Year, and certain annual benefits are associated with that status period.

Therefore, it is useful to keep three things separate when reviewing your account:

1. Your total redeemable SkyMiles.

2. Your current Medallion Status.

3. Your current-year MQD progress.

Can You Lose Delta SkyMiles?

Although Delta's standard policy says SkyMiles do not expire, that does not mean an account can never be closed or miles can never be removed.

Delta's rules reserve the right to deactivate or close an account under specified circumstances. They also contain provisions concerning violations of program rules and other account-related issues.

For an ordinary member who keeps an active account and follows the program rules, the key point is that December 31 is not a normal expiration date for accumulated SkyMiles.

How to Protect Your SkyMiles Account

Even though regular SkyMiles do not have a standard annual expiration date, it is sensible to keep your account information current.

Consider:

• Keeping your email address updated.

• Checking your SkyMiles balance periodically.

• Reviewing transactions for accuracy.

• Following Delta's current SkyMiles program rules.

• Keeping account access secure.

These simple steps can make it easier to notice account problems before they become difficult to resolve.

What Happens to SkyMiles If You Don't Fly for a Year?

Not flying for a year does not automatically cause your regular SkyMiles balance to reset.

For example, suppose you have 25,000 SkyMiles at the end of 2026 and do not take a Delta flight during 2027. Your miles do not simply disappear because you did not fly that year.

However, not flying or otherwise earning qualifying activity can affect your progress toward Medallion Status, because Medallion qualification is based on the applicable annual qualification requirements.

In other words, your redeemable miles can remain while your annual status qualification progress starts over.

Conclusion

Delta SkyMiles do not reset every year, and regular SkyMiles do not have a standard expiration date. The important annual reset applies to MQDs, which Delta uses to measure progress toward Medallion Status.

So, if you are tracking your Delta account after the start of a new year, do not confuse an MQD reset with the loss of your accumulated SkyMiles. Your redeemable miles and your annual Medallion qualification progress are separate parts of the program.

If you are planning future Delta travel, checking both your SkyMiles balance and your current-year MQD progress can give you a much clearer picture of your account.
