IB has a published fare for SFO -> VCE that would allow an AA award itinerary of
SFO -> LAX (AA) -> MAD (IB) -> VCE (IB).
AA has a published fare for SFO -> VCE that would allow an AA award itinerary of either:
SFO -> DFW (AA) -> MAD (AA) -> VCE (IB)
SFO -> LAX (AA) -> LHR (AA) -> VCE (BA)
BA does not publish a SFO -> VCE through fare. This means that an itinerary including BA across the Atlantic would not be allowed.
AB and AY participate in the SFO -> VCE industry (YY) fares. This means that an itinerary including AB or AY across the Atlantic probably would be allowed.
