A person who makes sure there are pilots and flight attendants for each flight going out, takes sick calls, answers ennumerable questions about everything under the sun and gets yelled at for other people's mistakes.
The crew scheduler made sure that there was a full crew to work the flight to Kalamazoo.
A minion of Satan.
A person who's profession is to make the lives of pilots, flight engineers and flight attendants a living hell.
That crew scheduler totally hosed me. I volunteered to cover a trip on my day off, and then she junior manned me on my birthday!
