"Razorray, good point - have we got too carried away with all the touchy-feely crm stuff? Logic surely says the more experienced FO who was in the seat he was used to should have taken over."
Its been reported that the PF (Bonin, the least experienced) was in the right seat and the PNF (Robert) in the left. Apparently Robert was woken up and then he swapped with Dubois while Bonin stayed in his seat. Presumably Dubois gave Bonin authority because he provided continuity when the crew changed.
