My son booked the cheapest Air New Zealand ticket to go PER-AKL-LAX and return.Now he has asked me if he can upgrade to get home with Air New Zealand.I have Velocity and SQ Kris points he could use and I am in Los Angeles. Can I do anything for him on these points and if so how? I have not used Air New Zealand for a decade so I have zero bargaining power with them.His flight is in 2 days time and he wants to keep his scheduled arrival into Perth unchanged.Is there a number to call ?
