Pill...experience noted, I apologize. Your initial post gave me the wrong impression (I was still processing the shock of this policy change). I totally agree with your last post.
Actually, after some thought, I think I would prefer an experienced 3-man crew (Capt, RQ FO, FO) to a 4-man (Capt, RQ FO, green SO, green SO). Sure, you'll get less in-flight rest, but at least both guys in the cockpit would have some time under their belts...you are paid more, and you get more rest at destination.
Goes to show what happens when rostering practices are solely amendable by the company....makes me wonder what other future changes might be on their drawing board. All while insisting that whatever they do it will be preceded by a full operational and corporate risk assessment and that safety is their first priority.
