Follow up:

My reservation was canceled by Asiana. I followed up with CS in Los Angeles and was told there was no availability on my return date, but I had flyasiana.com website showing seats open in the morning, as well as connecting flights through BUS. The CS said "I'm sorry, I can't do anything for you." and we ended at that.

I jumped over to koreanair.com and found availability on those dates, but would really like to have my *A account credited. So frustrating!

Looks like I might end up going with Korean Air
