I don't think I can check in online for this (could not on the outbound, SFO-LHR).
Two personal experiences/data points that may be instructive: both on one PNR - UA>BA.
When checking in with UA, I received both BPs.
On return leg when checking in with BA, no UA BP. Though they did put my checked bag through to final destination.
