Delta Air Lines’ Medallion Qualification Miles (MQMs) have long been a cornerstone of elite status qualification in the Delta SkyMiles® Medallion Program. One of the most distinctive—and often misunderstood—features of this program is MQM rollover, which allows excess qualification miles to carry forward into future years.
However, with Delta’s major SkyMiles program overhaul, many travelers are unsure whether MQM rollover still exists, how it worked historically, and how previously earned rollover MQMs are treated today.
This authoritative guide explains exactly how Delta rollover MQMs worked, what has changed, what options members now have, and how to maximize elite status value going forward, using verified information from Delta Air Lines and trusted aviation and consumer sources.
What Are Delta MQMs?
Medallion Qualification Miles (MQMs) were one of the three metrics Delta used to determine Medallion elite status.
MQMs Were Earned Through:
-
Flying on Delta and partner airlines
-
Premium cabin bonuses
-
Delta SkyMiles® American Express credit card spending
-
Promotions and accelerator offers
MQM Thresholds (Historical)
| Medallion Status | MQMs Required |
|---|---|
| Silver Medallion | 25,000 |
| Gold Medallion | 50,000 |
| Platinum Medallion | 75,000 |
| Diamond Medallion | 125,000 |

What Is Delta Rollover MQMs?
Delta rollover MQMs allowed members to carry over excess MQMs earned beyond their elite qualification threshold into the next calendar year.
This feature was unique among U.S. airlines and highly valued by frequent flyers.
Key Principle:
If you earned more MQMs than required for your Medallion tier, the extra MQMs rolled over automatically.
How Delta Rollover MQMs Worked (Step-by-Step)
Step 1: Earn MQMs During the Calendar Year
You accumulated MQMs from flights, upgrades, and credit card spend.
Step 2: Reach a Medallion Tier
Once you crossed your tier’s MQM threshold, additional MQMs became rollover-eligible.
Step 3: Year-End Calculation
At the end of the year:
- MQMs used to qualify for status were deducted
- Remaining MQMs rolled over into the next year
Step 4: Start the New Year Ahead
Rollover MQMs gave members a head start toward next year’s status.
MQMs vs MQDs vs MQSs: Key Differences
| Metric | Purpose | How Earned |
|---|---|---|
| MQMs | Distance-based qualification | Miles flown, bonuses |
| MQDs | Spending requirement | Ticket price, surcharges |
| MQSs | Segment-based qualification | Number of flights |
Important: You needed either MQMs or MQSs, plus MQDs, to qualify for Medallion status.
Real-World Example of MQM Rollover
Example: Gold Medallion Traveler
- MQMs earned in 2023: 72,000
- Gold requirement: 50,000 MQMs
- Rollover MQMs: 22,000Why Rollover MQMs Were So Valuable
According to frequent flyer analyses published by The Points Guy and Harvard Business Review (travel loyalty economics), rollover MQMs:
- Reduced requalification stress
- Rewarded long-term loyalty
- Encouraged incremental flying
- Increased brand stickiness
Unlike programs where miles reset to zero annually, Delta rewarded overachievement.

-
Used toward elite status under the new system
