I'll say that being able to list for a jumpseat and it's essentially a confirmed seat (FAA excepted) sure makes a massive difference in my QOL regardless of why I'm using it. I know there's a certain point where you probably never have anyone senior to you who shows up for it, but it really does make travel planning easier.
