Now im wondering how I should even go about attempting this upgrade. Ive heard its better to try and move from Premium Economy to Business than it is to try to go straight from Economy to Business

I think, currently, I can still move into Premium Economy just by going to the seat selection and choosing a premium economy seat and paying more.



Also, I currently have no miles at all in my air france/klm "flying blue" or whatever awards program. The way I booked these tickets was that I just transfered points over from a CC, and used those. If I attempt to upgrade via miles, would I need to preemtively move points over and just hope I get upgraded?
