Let's not get onto the same roundabout again, FSU. HISTORY - the collapse of Ansett, and the subsequent LOWER salaries being offered under TESNA - has proven my assertion correct.
Furthermore comparing salaries for the same job but different countries is futile, or would you argue that ALL pilots should be on the same salary as, say Air India pilots, or American Airlines pilots?
Quite obviously a British pilot would find it near impossible to survive on an Air New Zealand pilot's salary, conversely an Aussie pilot on an AA pilot's wage would have excess to spare, and a Japanese pilot on a Malaysian's salary would starve.
