Not to hijack the thread but I have had some weird reward partner availability as well.
I am booked PDX-LHR/AMS-PDX (all DL) and was searching for a return out of LHR. I found LHR-SLC-PDX on DL using the AS website with the last segment in Y. Since I already have the reward booked, I called AS. They could not find the SLC-PDX DL flight even though the website was showing it to me. My only option was to spend the night in SLC and fly Horizon the next morning. I ended up just booking LHR-SLC to at least hold that seat.
This has happened on other searches recently as well. I am not sure why the phone agent's view of availability is so much different than the website.
