Actually Air France doesn't fly to SEA.
The French newspaper 'Les Echos' had announced Air France was looking at DFW, PHL and DTW for the next years. Now CDG-PHL has been opened, we should see CDG-DFW and CDG-DTW soon. Even more with the current orders for long-haulers and with the planned growth on North America (Air France has annouced this is their focus-market for now, and they are keen to grow there).
As for DEN, Mr. Spinetta, AF's CEO, had announced DEN wouldn't be opened "before 2003". Also Mr. Webb, Mayer of Denver, has been courting Air France for a DEN for quite a qhile now. And according to Denver Post's sources, DEN would actually be on Air France's list, but "not at the top" for now.
Will the blow of the cooperation between Lufthansa and United make DEN move higher on Air France's list?
Wait and see...
