Thats your opinion and its noted. My thought process with this post you are noting above is some guy/girl is about to fly from NYC to Tokyo and thinking of going on AC.
You want me "to offer any insightful information." Well this person could be out 3000 + and frankly AC is hit or miss. Some AC flights are great, some flights are average and some are downright ridiculous. Its my " offer of any insightful information." to the OP to avoid this airline.
Its not worth flying on this outfit unless its free, in my humble opinion.
Anyways you are right about each airline having ups and downs. I just feel AC has a lot more downs than most.
