Caribbean boy: Our OZ services are not operated at a loss as we pool resources, profit and losses with QF, as for the other destinations you mention the operating or not is dictated more by market, economy forces more than just cabin crew wages-allowances.
It is not simply an arrangement where Qantas and BA throw the lot in the pot, and take the profit 50:50, but one where it covers specific routes and is adjusted for cost inputs as well and revenue generation. I know nothing further of the specifics, but find if highly likely that one party could make a profit from the venture while the other, with higher cost inputs, is not.
