I am looking to book a trip from Toronto to Auckland then to Papeete. I want to use my AeroPlan air miles and fly business class. What are the better ways to get such tickets or are they even available. The rules seem very different to what I am used to so I find it very confusing to get what I am after. Time frame is March/April 2018 or Nov/Dec 2018. Is there an easy way to tell availability? what about using star alliance partners?
Any and all help appreciated.
