I need to add middle name in Qantas APIS system. I have middle name in my passport but somehow missed in Qantas APIS. Also there is no middle name in my tkt. from Toronto to Melbourne via Vancouver and Sydney return via Los angles. *I tried to contact local Qantas office in TORONTO. but they told they dont represent Qantas anymore.*Tried to call Qantas Au office , more than * hr waiting time.*Which telephone no. I can contact in North America to change APIS and middle name in my Qantas tkt
