I don't believe this is correct. The Y/B instant upgrades that (I believe) you are thinking of does not apply on this route. You're still looking for R inventory for an upgrade w/ Y/B fares on non-CPU eligible routes, which includes SFO-LHR. The usual co-pay does not apply because it's a high fare class.
