I believe Delta iDine still posts MONTHLY. October charges would've worked OK, but too late now for mid-November posting.

Edited to add:

Delta's online booking bonus posts 10 days or so AFTER the flight credit posts. However, the flights themselves post just about as soon as the flight is officially closed; I have never, ever had a DL flight not post within 24 hours of takeoff. This is one area where Delta is way ahead of the rest.
