Totally PortiaEliot !
At the end less money for the AmexAF for sure on my side too...
Still interested in any other tricks to work on... (other Europan AMexAF)... I guess DutchAmexKLM is the only option for the moment... Until this changes too... Sooo not cool.
I would have thought that maybe the "plat amex" (500eur !) would have maybe been their marketing trick to keep status miles for them... or for AF "only" purchases...
Would have been somekinda "ok deal" for those for whom it matters... But seems they don't care about anything like this !
