AIr France will get you to your destination. After that, all bets are off. In my experience, the cabin crew is bored, at best, and seems not to care for the passengers and performs their duties in a perfunctory fashion. For trans-Atlantic passengers, that just isn't good enough.
On my recent trip, the flight was unable to land at Florence - was diverted to Bologna (although somehow the fog that caused us to be diverted did not deter my wife's flight, nor my sister-in-law's flight which were within 90 minutes of each other. Once in Bologna, Air France took nearly an hour to decide to send us by bus to Florence once we picked up our checked baggage. However, after over an hour, the baggage never showed up and we were finally told that it had gone to Florence (I wonder how that happened?). We have a nice bus ride over the Apennines (which I don't regret - very scenic, nice bus), but in Florence, once again had enormous difficulty getting our baggage. OK, so things happen. On my trip back to Boston, baggage was again a problem. Arriving in Boston, we went to the assigned baggage carousel. After 10 minutes an announcement was made that we could pick up baggage at a different baggage carousel. We waited there 10-15 minutes and were directed to go back to the original baggage carousel where bags finally started coming out after 10-15 minutes. Of course this may not have been Air France's problem, but Air France took no ownership of their passengers' confusion or irritation.
This may seem "ugly American", but it seems like a flight going into Boston could have a cabin crew who speaks more English and overhead announcements could be made in English that is understandable - not so heavily inflected with a French accent as to sound exactly like French.
And finally, boarding for Boston, AIr France handed each of the passengers an immigration form in French. A) it makes some sense to hand out a form in the language the passenger speaks/reads; B) they are unnecessary, at least for Americans, who must use the kiosks to answer the questions. My wife tells me that Delta didn't even hand out the forms - they knew the forms were unnecessary.
All this indicates to me a pattern of lack of concern for passengers.
