No effect on:
Safety
Oh yes there is a potential effect on safety!... and to that end answer me this... i.e. how come when we took on the crews of what had been a low cost European carrier - the standards of operation we found amongst a good many (but not all) of its crew was quite appauling? So much so, that even after spending a small fortune on 'retraiing' them in the sim, some of them were dismissed?!
But then, such is the demand for pilots - much in part due to the growth of LoCo airlines - that some of these people have since been re-employed and are, this very day, flying around in the skies of Europe.
Imho, pilot training & standards are struggling to keep up with the growth.
