My understanding and what I have been told by several people differs from what a travel agent is telling a friend of mine.

All flights under the same booking number:
A flight MEL-SYD-YVR-YLW
Qantas MEL-SYD then
Air Canada SYD-YVR-YLW

You can check the bags in MEL all the way through to YLW but will need to collect them in YVR go through customs and then bag drop for the domestic flight. That I know is 100% correct!

However the travel agent is now saying that all boarding passes can be issued in MEL for the Air Canada flights as opposed to checking in at SYD with AC.

I don't believe this is correct, definately wasn't on my flight in January and from what I have been told nothing has changed with the QF/AC systems.

Thoughts ?
