Huh. Well, HQ is certainly taking advantage of codeshare relationships, aren't they..
To think, you could fly YHZ-SYD on an HQ code the whole way. And the funny thing is, AC would probably put you on the same routing (YHZ-YYZ-YVR-HNL-SYD).
But how is HQ going to get the CA-AU route authority? I didn't think we had open skies yet..
