Jumpseating...
Yes...it depends on what company you are with.
Marketing pin-heads were constantly changing the rules and trying to charge something. As a commuting pilot, you were the last to know this and sometimes got the backlash. For example, when I was there...they tried to charge the Jet Blue guys for jumpseating...guess what Jet Blue immediately recipricated. Flight OPs VP quickly jumpd on this situation to save the day.
