They've either totally messed it up now or they've seriously cut back on what classes earn miles on AC. The following is what they now list on their website:

Economy 100%: K、E、G、N、P、R、T :
International routes excluding Canada < - > U.S.

No miles: X、D、W
K、E、G、N、P、R、T :
Domestic routes within Canada and Canada < - > U.S.

It really doesn't make any sense at all as it's not clear what they mean by their "International routes" and "Domestic routes"...

Do all international routes excluding routes between Canada and the US earn 100%? Or do just international K,E,G,N,P,R,T classes earn 100% Same for domestic routes or international routes between Canada and the US. Do they all earn 0% or just the same classes they list or what?

If anyone from OZ is reading this, please redo the AC mileage as it makes absolutely no sense with what you've done.
