Ah, I was afraid of that. Eventhough according to the AC AP website L accrues miles I was worried that it might get mixed up and if the Boarding Pass would only show the NZ flight number there is a good chance for no mileage.
As mentioned in my previous post I will book now seperately as the NZ US website states very clearly which fares earn *A status miles and which ones don't. Let's hope by the time we get the Nonstop to AKL from YVR the Canadian website will be set up similarly.
Thank you KVS really appreciate it.
