Thanks for all the responses! I have flown AC business quite extensively but what interests me is flying on new LH metal (A340) and seeing how good it will be.
LondonElite, my experience with 767 business has mainly been domestic. In those, there aren't any personal tv's and the seats are definitely worn. Maybe it's different for trans-atlantic 767's? However, when I do trans-pacific business, AC has always flown me in A340's and I've been quite happy in those.
