Here is as strange one. Daughter and family, four people, flew BR direct YYZ-TPE, single booking for the four of them. Two of them got the aeroplan points right away. Third one showed up next morning. Fourth one not yet. Three of them share the same surname, i.e. her husband. The one missing is one of the kids.

This said, would not surprise me if the points would show up tomorrow or the day after...
