How can the OP even call ANA (NH) and tell them what happened when he doesn't even know the full account number to reference?
NH isn't going to know what NH43887xxxx is since half the account number is missing. Nor does NH know who owns the account the OP is calling about because it's not in his/her name.
Unless CA gave up the entire NH account number I don't see how calling ANA does anything.
I'm in the middle of an Air China trip (within Asia) and my outbound flights haven't credited yet but that was 4 days ago. My UA number *does* appear on the BP.
