I am never sure what credentials one is supposed to have to be CEO of an international carrier - however I believe Mr Dixon was a political journalist back in the 1970's. I worked overseas with a woman who had worked with him in Canberra as a journo, and even she cannot believe how he made the quantum leap to his current role.
No doubt he would have all the right connections even if he didn't have the business background or experience - and he could be his own "spin doctor".
Quite a frightening concept really - it seems that the job has already been outsourced!
