Unfortunately, it seems the reverse is not true/running. Arriving at Hall L, I had to go thru contrôle sûreté, and then the signs direct you to passeports at 2F before going downstairs to the navette to 2G.
Temps de parcours : 40mn.
Arriving a little late from the US due to conditions météorologiques in the US, makes for a bit too little time at the lounge.
