*That* has been the case for a while, and I'm familiar with it. What's new and surprising to me is that I've checked in for a flight where I have *not* yet been upgraded, but I don't show up on the list. And I'm definitely eligible. So I can't tell whether I was left off, or am not showing up because I checked in more than 24 hours before (connecting flight, checked in at T-24 for my first leg), or what.
