It sure is a pity the A346 is taken off AKL. I did a search on all 777-200ER destinations and I think I found out where the A346 is going to. It is going to MXP.
As for the questions regarding the C seat out of AKL, The 777-300 and 777-200 can barely reach AKL, thus it seems only the 777-200ER will go there. Anyway, the 772 and 777 have got the same seats as the A346 and the 773 getting the new seats soon with 1 out of 6 refurbished already.
