Also, note that this post assumes airline perspective, not skymiles member perspective.
While it might incent people to spend additional dollars this year, it could equally incent them to spend less the following year and instead rely on rollover MQD's. Further, this would include flyers who would have booked DL anyway without the rollover incentive. I'm not seeing a compelling case here.
