I had a reservation with AA for a 4 continent ex Australia. My route was syd-cns-bne-chc-mel-lax. AA Agent called and advised that this is not permitted since I have two international Departure???. I think that I am doing 1 international departure (Australia to New Zealand) and one arrival (New Zealand to Australia) . Am I correct. Can I argue that point??.

P.S. when I return to Australia I return from Nrt-Syd
