Crediting NZ flights to other programmes - ticket number?
Having ticked over recently to Gold Elite i've decided to credit a few of my recent flights to Aegean.
Problem is, A3 ask for a "Ticket number" which they suggest should be 13 digits long. No issues with my European flights (they all have the number printed on the boarding pass) but I don't have a ticket number on my NZ boarding pass.
Does anyone know how I might find this, or how I might get around it?
Thanks.
