I flew Air New Zealand HK to London early November and the points never showed up. I filled in the request for miles with United Milage Plus website. About 2 weeks later I received a letter in the mail that denied the request for miles. This issue is what prompted me to search online to see if anyone else has faced this issue. Is it possible to get miles on Air New Zealand at all?
Perhaps in the future I will try Air China, but I am a little afraid of a long haul flight on that airline.
