The seats on their 747's are very narrow. The F/A's all speak English and were very nice. I avoid flying them because I was supposed to check my stroller in and connect in Paris without it. I had a supervisor called and was allowed to keep it that time but avoided booking them after that. Obviously, this doesn't apply if you don't have kids.
There are always tons of Americans on their flights. Right now, I'll venture that there will be more French visiting the States than vise versa because of the weak dollar.
21 years ago I took Air France to fly to France to study. On the way back, the F/A's were showing me their charts, talking about their job...and a couple months after returning, on a lark I did another airline's interview and passed. I flew for 13 years as a French speaker on two American companies and travelled all over the world.
Later on I flew out of Charles de Gaulle airport, met my French husband, etc. and have been here in France 12 years. I can't credit Air France directly but it was a positive influence...
I will have to warn you that when I worked at CDG airport, the place is basically one roving strike. Our work greeting was "Hi, how are you doing? Who's on strike today?" which the reponse was "Hi, fine. Catering/catering truck drivers/airport cleaners/aircraft cleaners/baggage handlers (that was fun), another airline" etc.
Just be mentally prepared to see French "Industrial Action" up close.
I've flown them a lot within France with varying degrees of success. But they are *always* nice, and really great with my kids.
So, to sum it up, if it weren't for constant strikes, stroller grief and those skinny seats, I'd fly them again.
