AFAIK operating carrier gets full control of the relevant chunk of PNR at T-24. At that point they can make changes to the flights in that part of the trip.
To add clarity, let's say there is a return ticket which goes A-B-C-B-A
At T-24 of the A-B flight the operating carrier will have full control on A-C (even if B-C is on a different carrier).
