All-NW (metal, flight number, etc) domestic should post the 2nd day after the flight, including some 1am red-eyes. So flights form 5am-1am should post on the 2nd calendar day. Should also work for NW metal/flights that are international, my DTW-FRA flights posted the 2nd day also.

Throw in code-shares, other metal, etc, and it's all up in the air. There's some predictability, yet also some oddities.

That's about right, but I dont accrue Miles on NW much anymore. I accrue them on KE Skypass, as I have over in Korea for a half a year on university exchange. I have also been a KE Skypass member from since Oct. 2006.. from then until i've accrued ~31,000 miles. of which ~23,500 miles were on KE. From past experience, the miles for KE were credited immediately at checkin and then adjustments made to the actual earned miles a few days after to adjust for the route and length of actual flight.I have accrued only one NW flight on KE Skypass, which was credited in about 2 days after the flight. NW WP, from what I rem. the flights took about 2-3 days to appear. That's cool with KE, when you check in, on the bottom of the boarding pass it shows a brief statement of your Freq. Flier account.. like how many segments flown, total banked miles, total actual "Remaining" balance and how many miles will be accrued for the flight
