Air France have now started a LHR-LAX service a 7 days a week departing at 17.00 and arriving in LAX at 20.15 PT return leg departs LAX at 20.25 and arrives LHR 14.40 (next day), the route is currently serviced by Boeing 777 aircraft.
Hope the service and amenities have improved since I flew CDG - LAX a few years back. Wish I'd taken the UA option I'd been offered..
Good to see some more competition though..
