Looking at the following Aeroplan booking in J for 2 passengers.

YYZ-LHR
LIS-YYZ

When I do multi city booking, each leg works out to about 60k in points for lowest J reward. Should be about 240K in points for 2 people total.

Instead I get a total of about 337K points (plus the taxes).

I see you can't book multi city on the app.

Any thoughts? I guess I can book each leg individually and get the right point total, but that means 2x cancellation fees if I change my mind.
