Maybe i have but i tried to do it online first but i couldnt put in a stop over at cdg. Hence i called up.I think you have confused yourself massively. It is very simple to check the amount of points required. SQ flights only - check the SQ table. Any leg *A flights (even if you have SQ flights in the booking) - check the *A SQ table. For arguments sake always look at saver availability for what everyone would call the normal cost.
It won’t double by using a *A award.
The person i spoke to sounded a little reading off a script. So It didnt surpise me when i asked why would the points required double i didnt get a proper reply. Might tinker online again
And yes always saver for me!
Paying double points would never happen in my world
