Same would go for IB I presume. MIA is non-Schengen so to T4S and BCN would be from T4. That is also a horrible connection
BA's BCN flights operate to and from LHR T3, and have done for some months now, which makes for a much better connection in this situation.
Whilst I appreciate everyone's individual experience may differ, for what it's worth I've always found connecting between MAD T4 and T4S a breeze.
