Hans Blix,
I would bed to differ there. If you go back to the days of competition with Ansett NZ (R.I.P), without stepping on toes, there was often much talk about the relative profitibility of the Air NZ domestic operation. At the time Air NZ used to often show in it's annual that in spite of it's majority share of the domestic main trunk market, it didn't make much of a profit on domestic maintrunk turnover at all. From memory around 3-4% for most of the 90's. And this is back when it was operating ancient outdated third-world -200's and on the books they would have been pretty cheap.
