I'm betting SLC too, they are pretty much the worst. Both ops and the gate agents think they own the jumpseat. Had it one time where I knew a jumpseater was waiting, called ops to tell them to come down, and they said that we are not accommodating jumpseaters today (mind you, we were still 10 minutes early at this point) Well, we basically told them that we were not accommodating brake release until jumpseaters are once again accomodated. Turned into a standoff, delayed the flight quite a while. Eventually the chief got involved, and low and behold the jumpseater came and off we went, over a half hour late. It was pretty ridiculous.
