Yes K.B, I would put money on it.
I thought that was a pretty obvious reason why EK went into this QF/EK deal to start with... to utilise all the unused slots of QF, globally and access more of the Oz market which is lucrative for them.
I'm afraid it may all be just a one way road... if wet leases... BUT given EK can't get enough trained/qualified crew & trained in time (bottlenecked), it may work out as dry leases.
Might see what that dick lil'Tommy Waterhouse has on it
Happy landings
