Just be aware that if you have benefited from an AP error, you may get caught out if you decide to make a change later (depends upon how observant the agent is).
My overall charge was YYZ-Middle East as you mentioned, however, it was on J, so I was actually charged 82.5K (165K round) instead of 77.5K (155K round).
If that's the case, I'll definitely need to contact them about this.
Interesting enough, I had no idea that zone prices can be more expensive in one class but cheaper in another.
