I flew an itin in early Sept that was all NW except for one DL leg. I checked with the gate agent prior to boarding the DL flight, and she confirmed my WP number was in the record. My Skymiles number had never been associated with this itin - it was all ticketed by NW.

Several weeks went by, and miles still had not posted for the DL leg, even though all the NW legs had posted. I emailed Talk to Us, and they immediately responded by posting the miles and sent me an email. The message in the email said it was pending internal processing, but my account info on the NW websit shows it as posted. I didn't have to fax a boarding pass...

I was not delighted by how long it took for the miles to post, but it was nice to see such a prompt response from NW CS!
