I also believe that SFO load factors are down/haven't recovered post-pandemic as well as other hubs (not a JL specific observation).
The second LHR is currently a 787-8. And while it often books out, I am not sure it is candidate to jump to A35K capacity. When the first two A35K came in, or or rather was planned to come in, JL41/42 was briefly scheduled to become 77W. But I think apart from a few flights in the expat going home for Christmas period it went back to the 787-8 when the schedule was readjusted for the delivery delays.
