That I knew. There's not much to earn on the LHR-BCN segments, but wanted to let the OP know there's still a lot to earn booking VS US-LHR.
The OP might be able to earn Avios or even AA points on the BA segments. I was able to earn some UA MilagePlus points when KL moved me to LH due to irrops on a DL award ticket!
