I bought two separate tickets one on tg from Bkk to hkg. And a separate ticket(ac world pass-Asia). Upon check in with tg for my Bkk to hkg flight. I asked the agent if they can interline my baggage to air Canada to yeg. Not only did they tagged my luggage all the way to my final destination also thai has checked me in for my air canada flight( I didn't not do advanced check in online) and printed me my air canada boarding pass. To my surprise, the boarding pass also shows ACSE on it. I never thought tg can check me in on a separate air canada ticket departs from a different air port. Very impressed. I have attached a pic of my boarding pass here. Maybe time for ac to upgrade their system....
