While I might not share the same jumpseat militaristic attitude as others, GoJets is far from scabbing, BUT a message does need to be sent to all management types that this kind of end around stuff will not fly (pun intended!).
Before anyone gets all up in too much of a tizzy, GoJets is not all the far off from CRJ and ERJ "regionals" flying old mainline routes that were "lost" because of furloughs and fleet reductions. Take a long hard look in the mirror before you go and start a jumpseat war with a GoJeter, plus I don't think GoJets has many reciprocal jumpseat agreements, and that would be the more professional route to take if faced with the situation.
