I've tried searching for this information, but the FT search function keeps giving me a page cannot be displayed error...

What is everyone's experience of how long it usually takes for missing miles to be credited after mailing one's boarding pass to the Aeroplan centre?

The miles have not posted for my August 3rd LHR-YYZ flight, and my experience is that if they aren't there within three days, they probably aren't going to show up. I've let most of my missing miles slide this year, since they were all for YYC-YVR flights and didn't seem worth following up on, but I'd hate to miss out on 3,500 status miles.

Also, why is it that it NEVER WORKS when I try to credit missing miles online?
