Does trying to eUpgrade one leg of a multi-stop flight mess up the booking information for everyone? Its happened a couple of times for me now, the latest flying YYC-YVR-ZRH-VLC next week, waitlisted for PY YVR-ZRH, and now "my bookings" only shows YVR-ZRH. All still there on cowtool and the app, but first and last legs have vanished on ac.com...
