Call me naive, but I fly Air France regularly to the US East and West Coasts. The only "incident" I can report was some serious delays on multiple legs of one return trip to the West Coast. I was in no hurry, however, and after penalty payments received I was in the black by about 1000 euro. Other than that trip, things have gone relatively smoothly and comfortably. Recent trip trip to IAD was flawless both ways.
