Crewing have always been the poor relations to Operations in both pay and working environment. Crewing is THE black art and can be tremendously difficult. "We need a crew for the blah, blah", shouts the ops controller, as he/she puts his/her feet up waiting for the miracle to happen, and as frquentely happens, no SBY's. So the old boy network swings into operation as the the crewing person rings round to dig up a crew from somewhere. Definately in my opinion the most undervalued dept of any airline !!!!!!
