I am a OW Sapphire and flew CX several times within the last 12 months. I added my AS # to all bookings and the # was printed on all boarding passes. However, the miles haven't been posted in my AS account, despite my follow up emails (with images of the boarding passes)to AS.

My brother has a similar experience with CX though he banks his miles with BA.

At this point, what can I do? Thank you.
