If JQ and QF are truly separate airlines someone should go after them for illegal trade practices: it is obvious that "Qantas" determines the where, when and for how much of both QF flights and JQ flights, and the two "airlines" are not separate at that level. They move flights from one to the other as they see fit. Is this legal? Ethical? Fair? I don't think so. If course IMHO, IANAL.
