Well said crew rest. At the end of the day airlines exist to make money.A big fast Boeing is fine if you can fill it up with punters and freight but if you are developing a new route or times are hard reduced fuel burn can mean the difference between profit and loss,and that can mean the difference between having a job and being down the road. Its a question of horses for courses.All this "real men fly Boeings" may make some people feel good about themselves but is totally irrelevant in the real world.
