A slight tangent to the thread to hilite captains authority and the fact that the captain owns the jumpseat, not crew scheduling. If pilots allow scheduling to usurp that authority, they will in a heartbeat.

Why a captain (little c) would allow a deadheading pilot in the cockpit jumpseat is beyond me, when a simple "I'm sorry, the jumpseat is not available" will do.

Of course a pilot should never let it get go as far as resolving it on the jetway. My question to scheduling would be "were are you going to lay me over and what's my reservation number for the next company flight back to base?".

We truly are our own worst enemy.
