If this was a topic that had merit, then someone sufficiently concerned would surely provide this information to the public.
One can only assume either there is not that level of concern, so no-one has spoken out; the respective unions do not feel the need to speak out; the regulator is satisfied there is 'no associated risk to flight safety' (as the parrot said); and in any case, the public are not interested / do not care.
Cheap chocolates are tempting and very tasty.
Cheap flight tickets are too good to miss out on. Many people I know fly exclusively with one loco airline, as they know they will pay rock bottom fares - they do not care about the current situation; they do not care they always get back at 3 AM, etc, etc.
Who cares how they can possibly do it so cheaply, members of the public?
