I searched but couldn't find answers on BA's website.

I have BA points and want to use it to book 2 business class award ticket from YYZ to ACA. I think AA is the best airline for this route.

Can anyone tell me how many miles I need? From BA's website, I think Mexico falls under North America, but I couldn't tell.

Also, is a stop-over allowed? I would like to stop over San Francisco on return flight if I can.

Thanks for your help.
