I appreciate any feed-back, but my actual question has still not been commented. OZ are operating two 744 (full pax) with identical upgraded seat confirguration, and three 74M (mixed) of which only two are with upgraded seat configuration (similar to upperdeck of full pax version) and one with old style seat arrangement, as indicated on Asiana US homepage.

Is the none upgraded 74M still flying in OZ fleet after introduction of new 3-class 777 and latest changes in schedule taken place Ultimo Nov / Primo Dec, thanks.
