I am having trouble understanding this issue. We are new members so don't have any points as such but will get 5.000 miles when booking economy tickets to either Madrid or Barcelona from Sydney. So on the day of our flight can I enquiry about upgrading to business class and pay for the miles or does the upgrade availability only apply to people who have lots of points.
Does this work out cheaper than booking a business class ticket originally.
I could have misunderstood the whole topic and would be grateful for clarification.
