I had some difficulty requesting my upgrade for YVR-HKG-YVR because Amex had used my first, middle and last name on my ticket but my Asia Miles account only has my first and last name on it. Calling Asia Miles was pointless since they left me on hold forever. Anyhow was finally able to request the upgrade online by nominating myself as a companion using my middle name.
What surprised me however was it was only 15K Asia miles each way, when I was expecting 20K. Thought I would share in case anyone else was considering that upgrade.
