Great topic and i like all the contributions here,i think there are so many factors that contributed on this life style(FATIGUE) one that i have seen my self is the state of the art computerized sys that those airlines use at the moment, the companies ask the to have the most utilized rosters for pilots so they can save money wile in the old days it was done manually.and this act cant happen if there was a union,the FTL have to change with the change of the industry itself.
