I have secured business class seats one way Brisbane to Vancouver in january next year with Air Canada but at the time I didn't have enough points for the return flight and it was too early for it to be available. I now need a return flight either direct from Vancouver or via LAX with Air Canada, Qantas or Virgin but as there is no availability I will have to purchase these. These airlines all want nearly as much for a one way ticket as a return ticket. Is this normal or am I going around this the wrong way. I was hoping to get an upgrade then.
