Excuse me, how can I inquire about the information of the purchased air tickets in Air Canada official website according to the air ticket number or passport number?

I can only find what you ordered on BEA Canada's website. If you buy them through a travel agency, you can't find them online. Call the Air Canada hotline directly, and you only need to provide your own ticket number to verify the authenticity of the ticket.
