For $450 you will get better value from a professional recruiting company such as the ones mentioned. They don't have to be familiar with the qwerks of the aviation industry to be helpful. In fact it is better they know nothing at all about the industry. You then get a completely unbiased approach.
The interviewers at airlines such as Cathay and Qantas are very familiar with the stock standard answers that this guy teaches you and on one occasion I know of, actually went against the person. Failed the interview, went and saw a recruiting professional, came back 12 months later and got through with the comment from the interviewers of "you have done a lot of preparation since we last saw you".
This course will not help you in an interview nor will any other that teaches you to answer questions with standard replies, but if you want to present a professional image to your future employers, don't insult them, spend your money wisely and see a professional employment consultant.
