I'm intrigued by the suggestion this will attract onboard worldwide connections.
I've just had a look at several worldwide routes on several dates after the 31st March and the best option, each and everytime in terms of cost and time, is to go via Amsterdam with KLM.
Unless Air France start operating it with their own equipment, and / or put it on their website and price accordingly, with decent connections, I can't see this route attracting much in terms of worldwide connections?
Certainly most would either drive to Heathrow or go via Amsterdam rather than buying a separate Eastern ticket and then onward travel from CDG.
