Why shouldn't the airline take the flack for there own incompetance. OK its not the Cabin crews job to ensure the bags are on board but it surely is the Captains responsability to know whats on his aircraft and what isn't. The Captain should never have left before the bags had been loaded. It caused untold inconveneiance for many pax. I have had bad experiences with Ryanair and they will never get me as a pax again.
