Alsacienne, I think maybe if you look at Summer Breezes comments, she was talking about a flight last Thursday which was indeed affected by strike action over France. Also I think you will find that there will be strike action again this Thursday 4th November - just tapped 'greve 4 novembre' into Google and comes up with a lot of info including -
Greve Air France 4 novembre 2010 : Trafic perturbé (temps réel).
Prévisions trafic : Grève à Air France le jeudi 4 novembre 2010 contrela réforme des retraites ce qui annonce un trafic très perturbé à Orly, Roissy et dans toute la France. Les syndicats CFDT, CFTC, CGT, FO, Ugict-CGT et Unsa estime que “Cette réforme résonne comme une double peine à nos yeux.
Air traffic has been affected quite heavily but I suggest to anyone due to travel by plane is to keep an eye on the carriers website ie Ryanair, Easyjet etc as if they do decide to cancel, the info is normally placed on the website straight away.
