sorry if this is really stupid, i don't know much about alliancesand the like, but....
wouldn't there be a benifit in QF/ANZ having a finger in each pie so to speak, they get the traffic from 2 alliances rather then picking one and splitting the traffic between them?
and does code share allow, fo example, a oneworld pax to fly on a QF flight number, but on an air new zealand aircraft?
i'm probobly way off, but i would still think there is a benifit of the QF/ANZ tieup having both alliances involved instead of one
