AS staff is probably overextended due to merger and just wants to get you off the phone. I guarantee it won’t post automatically if it hasn’t by now. I’m currently being patient and waiting the 6-8 weeks for my Aleutian Air flights to post (I know they won’t). I have it on my calendar when to call back.
My last EI flight posted in 4 days. If it didn’t post it was likely a computer error.
