In addition to CDG-HND, JL has also released at least two on SFO-HND. We booked 3 days out, altho they may have been there sooner (I hadn’t been checking). I believe it was at F3 when I booked, but morning of the flight, there was only one other seat “sold.” Not the A350, but the SFO flight is still long enough for the full experience and we were pleasantly surprised by the BA first dining room at SFO.
