Hope someone can help. I need to add a return flight to my current outbound 241 Sydney flight and given the state of the call centers, I am in doubt I can get through to someone at midnight. I am looking to do the option in the wiki and book the return leg separate and give them a call in the morning to try and get the 241 retrospectively applied to the booking.
The challenge I have is that I don't quite have the 300k avios to do the initial booking but I could do one of the pricing options of paying more cash wise and hence less avios. Does anyone have any knowledge or experience as to whether this would work and I could get the 'extra cash' that I paid refunded when the 241 is applied and the avois amounts adjusted? or would it simply be a case of half the reduced amount of avios refunded and I would not get any cash back.
