So current state of affairs seems to be that AC availability is mostly phantom or not showing. EY appears to only make J flights available to partners 2 months out, which you can search on AA and then you'll need to call in to AC and these SHOULD be bookable over the phone. Anything further out than 2 months on AC.com is likely phantom, even if GuestSaver availability exists on EY.com.
