Fire Left, A "Twitchel" bid {spelling?} Was named after a Captain Twitchell of AC who like many of us objected to flying with smokers, thus the F/Os bid a day after the Captains bids closed so they could bid around the nicotine addicts, of course it was also a way to avoid folks you just didnt want to fly with.These days of course all one has to do is to punch the persons employee number you wish to avoid into the computer and it will take care of the problem.
