I would have thought that any single bad apple carrying out incidents like this would be seen or noticed by another member of the CC..ie not an individual.
I was not attempting to tar all CC with the same brush, but the actions of a minority will impact on the perception of the whole. If a PAX boarded a flight and found something not right who would get the blame in their eyes?
Even the current dispute is unclear to the majority of members of the public they see headlines of BA cabin crew on strike and to them it appears as if they all are.
Details are slowly coming out educating and allready Anti-CC striker public, but until everyone is fully informed, it would be silly to dismiss such sabotague actions as irellevant.
