1972 or 1973 London to Los Angeles

I may be wrong but I didn't think BOAC operated LHR - SFO, wetsbound, in the very early 70s.

I seem to recall the service routed eastbound through Tokyo and then to SFO, turning round there and then back across the pacific to Tokyo and thence to LHR.

I think SFO - TYO was quite a long sector for a -436 and a refuelling stop (Guam?) may have been neccessary occasionally.
