The other issue regarding this great leap forward from Airbus is that Lufthansa has already said it won't be going down that path as it doesn't meet their safety criteria. One issue they identified was the issue BB addressed and that was the time taken for the other pilot to get back into the flight deck and up to speed on a possible emergency. So I don't think Qantas is going to go down the Cathay path but more than likely align itself with Lufthansa.
