I don't dislike AF and I often take the non-stop SFO-CDG. They are known to be rigid, however. I have taken several domestic trips with them in France and when I show up at the airport earlier than expected because I finished my business, they refused to let me take an earlier flight than the one I booked, even when they have flights leaving every hour and they are half empty! (Elite status on SkyTeam partners means nothing to them.) This has happened to me so many times I don't even bother to try anymore. One just has to learn they operate under a different set a rules than we have, although I have heard Southwest is equally rigid about this issue here in the US.
