AF flies several different configs of 777 on the route, and they are in the process of switching to a 4-class layout on all of them with the introduction of the Premium Voyageur class. Look at the seat maps on AF's site. They won't have seatguru's sometimes-helpful comments, but they'll probably be accurate. I would allow for last-minute equipment swaps between PV and non-PV aircraft over the next few weeks, at least.
