i think that you will find that there will be "no" shuttle. And most premature to suggest that it will be AKL based crew.
I know that if i were management it would probably be the most "efficient" way to crew the flight but not if you wanted to have any level of ......no i am not going to go there.
Just be patient, i am sure that it will be a combination of crew as it has always been and not just AKL based as has been suggested.
