Going to be travelling to Sydney in May from Winnipeg. It'll be an Air Canada flight from Winnipeg to Vancouver, then ANA Airlines to Haneda to Sydney. Am I able to through-check from Winnipeg's airport with Air Canada all the way to Sydney, or will I have to pick up my luggage in Vancouver and then check in again there because the airlines change? If so, how do I go about checking luggage for an international connection once I've arrived in Vancouver? Both airlines seem a little vague on if this process would work, and seeing as I'm only allowed one carry-on with ANA I'm going to have to check luggage, so I want to make sure I do it right and don't mess it up.
Will the same process apply to the return flight as well? Same locations. Also all on the same ticket.
