Should I join the Aeroplan membership for crediting Air Canada flights?

I have just booked Business Class Brisbane to Toronto return with Air Canada. What are thoughts on joining Aeroplan or is it best just to add my Kris Flyer membership. Most of my points are with Qantas and Virgin and Amex Card. Thanks

Hi @greg2 You can use the below website to see which points you can earn on these Air Canada flights and then decide where to credit them.

If it was me, I would credit where most of my points are.
