This is probably one of THE glaring major differences between true Low Cost carriers and airlines such as QANTAS (aside from the low salaries of the coalface workers) - the legions of office workers sitting around computer terminals, or busily shuffling papers, overseen by grossly overpaid managers (each with their own P.A. - personal assistant) who hold "meetings" multiple times each week, whilst the real airline continues to be run from decisions made at the front lines.
It has been a long time since I have seen figures that give numbers of employees per aircraft, however it would be interesting to see how the numbers of BS Castle inhabitants compare with the number of "front line" workers.
