Yeah, I would have jumped on those, too. They might never open U or T for two days before Christmas. Since I've been hanging around FT, I have a much better clue about what's going on with airfares. Not that they make sense, mind you, but at least now I know that only seeing H (and empty planes) seven months out should be a sign to wait and see if the other buckets become available. (Or, more likely, looking far in advance and seeing T all the way means BUY, BUY, BUY!)
