I flew to RIC from YUL on DL last week. (I know, I feel like I cheated on UA LOL). On the way back, RIC-CVG I get off the plane and head for the ComAir terminal. By the time I go to the laptop lane (No Wi-Fi in ComAir) my miles were already in my DL account.
Amazing..

My flights from the week before took 3 days to post on UA..
