9W metal will get you to the East Coast (JFK/EWR/YYZ). You'll have to find code share options for the transcon to SFO.

Surprisingly neither SFO or LAX is in the online list of codeshare destinations that they sell. Other US options are BOS, ORD, RDU (!!) etc. However, there are also a ton of Canadian destinations, and YVR would probably be geographically the closest you can get to SFO on a 9W codeshare (atleast among the online bookable ones.) This routes via LHR with LHR-YVR on AC metal on a 9W code. AC has an excellent longhaul J hard product, with the J seat virtually identical to the herringbone 9W seat, albeit slightly narrower at the shoulders I found.
