My *G can't be recognized when traveling on some *A carriers like OZ, FM, and CA. But recently I discovered possible reason. I came across a CA check-in agent in PVG last week who knew the trick. Just ask them never to enter the beginning zero on the Airpoints card and NZ*G will be instantly printed on boarding passes. I am not sure what purpose the zero serves anyway. I have had some horrible experiences almost getting denied priority boarding and lounge access. It made me look like a total idiot for getting responses like "your card must be expired" or "our system can't recognize your status so we can't issue you with a lounge pass" or "please queue up like the rest of the passengers."
