Just on the point of US FAA dispatcher's pay, as it came up in this thread.
You might be interested to know that one of the chaps I am working with at present who has 20 years dispatch experience in the US, just interviewed for a dispatcher position with United Airlines last month, they offered him the position at a starting salary of $32,000 per year (UK 16,000). The days of high dispatcher salaries in the US seem to be over.
