Yes, Delta MQMs (Medallion Qualifying Miles) did roll over into 2023, marking one of the final chapters of the traditional rollover system. Under the policy at the time, any MQMs earned in 2022 that exceeded the amount required for the status level you achieved were automatically added to your 2023 balance to help you qualify for 2024 status. This was a supportive "legacy" benefit that made Delta's SkyMiles program famous for its loyalty retention. However, a grounded reality check for 2026: the MQM system has been officially retired. As of January 1, 2024, Delta transitioned entirely to MQDs (Medallion Qualifying Dollars) as the sole metric for status. Any "final" MQM rollovers from the end of 2023 were converted into either MQDs or redeemable miles in early 2024. While the 2023 rollover provided a "Gold Standard" head start for many, travelers today must focus on total spend rather than miles flown, a shift that has fundamentally changed the strategy for "mileage runs" in the modern aviation landscape.
