A11 unfortunately most people are not as enlightened as you! Most passengers want the cheapest seat they can get. Most airlines want to maximise profit. The CAA/ government gets rather a lot of money from airlines. So airlines get to call the shots. Because every aircraft accident that has had fatigue mentioned has also had some other factor, so fatigue is always just an "additional" factor, never the main factor.
There have been various reports done highlighting the problems of fatigue and fatiguing rosters, but the CAA stands by its "CAP371 is the bible, its been fine up until now therefore why change it" enlightened view.
In my opinion, it is unlikely for fatigue to be named as the major cause of an accident, therefore the flight time limitations won't ever be changed.
Most pilots will be extremely tired, if not fatigued, when operating a heavy schedule with numerous changes of report time and all night flights, it has become the norm.
I really don't see anything changing in the forseeable future.
