Today I bought return tickets with the following itenerary: YUL-YYZ-GCM. Now if I look at the online reservation it asks for the "Advance passenger information" for all passengers in the ticket.

I though that this was the case only for travel to the US. In fact when I open the API window it asks for a US address. Do I have to provide the information, or is this just a glitch in the AC reservation system.

Thanks

PS Booked in L with 50% status miles. H class was twice as expencive. M even more.
