Hi, I wonder if I could get some help.
I just booked YYZ to BKK with China Eastern and BKK to YYZ with China Southern, both in J.

When I was asked for my frequent flyer program it gave me the choice in the pull down menu for Aeroplan. I entered my details but I am wondering if I will get credit for the flight with AP. If not, does anyone know what program I should use and how to make the change?

Sorry for all the questions, just a newbie trying to figure things out.

Thank you.
