My Air France experience is not current, it’s from 2015 so it’s probably irrelevant. I have to ask DS, but as I recall there was no announcement, but the flight attendants hovered over him to the point he found it annoying. Of course he ate his own food, and I think they had some nut free prepackaged snacks, but I’m not sure. On the way back we loaded up on food in Warsaw, and there were no issues. (We flew NY to Paris on Air France, and Larks to Warsaw on Lot Polish, which was a fabulous airline, BTW).
