Now that Air France is in bed with KLM it seems that they believe they will be competing against themselves if they operate from the smaller UK regional airports to both the AMS and CDG hubs.
AF pulled out of BRS apparently for this very reason, with KLM Citihopper operating the AMS route as it also does from CWL, and I believe they have done so elsewhere as well.
BRS was lucky because BACX (now BACon) also operated the CDG route from there and simply increased their own rotations to fill the AF void.
Having said this it seems inconceivable that no-one is stepping in quickly to fill the CWL-CDG route.

Edited to say we seem to be together on the AF/KLM thing. Hope you're in fine form. I believe you are now away from these shores. Best wishes.
