Whether or not DMs typically get upgraded is highly dependent on the route, day of week, and time of day, as some flights are vastly more DM/360 and MM heavy than others. On my regular transcons out of ATL, I've had to use my RUCs to get upgraded as a DM 2MM. If you want to know whether you'll clear under the new rules, wait until after the new year and see where you land on the UG list. With the new upgrade priority, I'm hopeful that I won't have to buy F as I've been doing, but until I try I won't know.
