Seems the bad news works two ways.
I 'friend' of mine (actually, dumb as a rock, but from Texas so I can understand

) applied for a Captains position, received type training and completed line training.
Then, the crew scheduler wanted this guy to position to Anchorage for a flight.
He says...'No, I don't do Alaska' so he was terminated on the spot.
He is now personna non grata at several airlines...bad news travels fast, make no mistake.
