I had one dine with DL for their Pile on the Miles promo, and the "Go the extra miles" were posted when I first noticed it. For my main program, NW, I registered and met their qualifications, and the Extra Miles haven't been mentioned in my regular notices. Should I expect them to post when they go over to Worldperks on the monthly date? The difference being thet the DL miles go over to the main program more often?
