Just thought I'd let you all know. I was upgraded either yesterday or the day before (leave tomorrow). Of course, they didn't let me know. I went online to check availability of J and noticed that they had given away my Economy seat. My TA told me today that they had upgraded me. So, the moral of this story is a) stay up till midnight so that you can be early to call them (if you're Elite) and b) don't give up hope. At one point, they had no J seats even for revenue passengers.
