AS miles posting to OnePass
 

Does anyone know how long after you have completed your flight on Alaska do miles post to your OnePass account? Thanks.

I've had them post within two weeks. I'm not sure of the exact time frame. They do not post at the same time as CO flights post (but you've clearly already figured that out :p)

For the three Alaska / Horizon flights it took, it took about a week to show up.

I remember a post here saying that Alaska transmitted its mileage credits to other programs once per week and if you were within one or two days of that report, it may take an additional week.

I think it was Wednesday or Thursday they transmit.

Yeah, I remember that post too and I was trying to find it. I know NW miles post on Tuesday and I thought that Alaska was also on a Tuesday but I think you are right that it may be Wed or Thur.

AS miles post on Thursday for the previous calendar week.

So if you fly Saturday, it takes 5 days.
If you fly Sunday, it takes 11 days.
