To be very clear, Delta has made no hints or implications that MQDs rollover will ever happen. Obviously it doesn’t exist currently. But part of me wonders if that may change under the new system, and if MQD rollover may happen in the future.

Simply put, it’s very possible many individuals will find themselves in a position of clearing one status level (ie Gold), but realizing that they won’t have enough flying or purchasing for the rest of the year to earn the next level (ie Platinum). In such a scenario, without rollover, there is no incentive for additional incremental DL Amex spend or flying on DL. But if MQD rollover existed, there would be an incentive, as that earning would effectively be jump starting for the next earning year. So point being, there may be a financial incentive to DL to allow MQD rollover and incentivize that additional spend..

And obviously, if MQD rollover did exist, that might change the strategies we employ.
