I have a reward flight (utilising a 241) booked LHR-TLV return. BA have now cancelled the morning outbound flight and suggested the same day evening flight. I will ask BA to put us on the evening flight the day before, as I need to be in TLV by the time of the original flight.
I would also like to change the return from TLV-LHR to LCA-LHR. I can see reward availability for LCA-LHR, but I can’t cancel the whole trip myself and rebook as there is no reward availability for the LHR-TLV showing, so I’m relying on BA to make that change. If I wait long enough I’m confident that BA will cancel my return TLV-LHR as they seem to be removing one rotation on that route, but I don’t really want to wait until they get around to looking at June flight dates, the outbound is May.

short version - can I change the return portion departure point of a reward flight if BA change the time of the outbound?
