241 on 2 x one way flights

If you call to add the return, BA would just charge you the 241 avios pricing so there would be no need for a refund.

But if you want to benefit from lower taxes from GRU, you need to book it as 2 x one-way, request half the avios back for the return sector and hope BA don’t insist on re-pricing. You’ll retain 2 separate PNRs.

This doesn’t answer the OP’s question? They’ve indicated they want MAD-EZE on IB then GRU-LHR-GLA on BA.

Thanks for the info NorthernLass, would it be normal practice for BA to re-price this?

To the extent that you say you can already see the availability for the two individual journeys, you may not be able to reclaim the 50% as that is only supposed to be a concession for trips booked at T-355 when the return wasn’t yet available for booking. If it’s say, ten months away, the whole thing should be booked as one and repriced.
