So they actually issued me a new ticket with the W fare. I don't know much about the architecture of the fare classes. But if fare class comes into account for upgrade priority, I would think that the W is a higher class. So are you saying that it is not a fare class at all, rather on top of a regular fare (whatever was the fare class when I bought my ticket)? And therefore there is no class difference between WU vs. W?
