It would be interesting to know what the difference in benefits between DMP and DME actually is and (apart from VIP cases) what spend level is required. If I routinely did 2400+ miles I think I would be particularly interested to know as it seems (to me at least) that 2400+ miles is a lot of mileage to not be treated as top tier. And aren’t big spenders beyond this more likely to be flying GA anyways?
