Does the return milage take longer to post on a partner airline?
 

Is it just me or does the milage for a return portion of an itinerary take longer to post in a partner airline than the outbound? I am waiting for some NW miles to post in CO and the outbound posted in 3 days.... 7 days after my return I am still waiting for the return miles.... I seem to remember this from several other trips....

I have no experience with the specific combination you mention, but my general experience is that yes, it takes longer.

I've noticed the same thing. Give it another week and then call.

This appears to be specific to CO, so I'll move it there.

Okay.. what is a reasonable amount of time to wait for the NW partner miles to post to my CO account.....thanks.

NW used to send a tape to CO which posted every Tuesday (I think)...at least that's how it was 2-3 years ago. Call OnePass and ask if NW still posts once a week. If you just miss the weekly tape, it could take 8-10 days to post at CO.

I'm in China, and my outbound legs SFO-NRT-PVG on Sat 10/8 - Sun 10/9 had already posted by Mon 10/10 2 pm CT (Tue 10/11 3 am China time). So either CO posts NW more than once/week (maybe NW and CO have a more direct connection), or the tape runs sometimes Sunday or Monday now.

Hope this helps.
