Before I was a 1k I got several double upgrades--from coach to first on a three class plane. Since I have been a 1k I haven't gotten any operational upgrades. Of course now we always manage to get in first or biz, usually at the time we book. It would be nice, however, to get an op-up from biz to first occassionally.
Since I have been a 1k, I was once reseated in first on a 767 because I wanted to watch the movie and couldn't view if from my assigned seat 5A, so they moved me to 1C.
