So abit of a complicated issue for a newbie like me. our child is a dual japan and canada passport holder, with a different last name on each (mom's side and dad's side). we're flying from Canada to China and we'd like to use the Japan passport since it is one of the countries for visa-free travel.

It would be very simple if we just used the Japan passport all the way through. However, the problem is we booked under the child's name under the canada passport. So to the airline, i'm going HAVE to use the canada passport.

I worry that the airline will deny boarding because the child doenst have a visa, but then I will say she doesnt need it because she will use her Japan passport when we arrive in China to get in.

What should I do?
