Code-share PNR is different. Even though CX and BA both use Amadeus, there will be a distinct underlying code-share PNR for CX's operating segment, as the "original" PNR only has the BA marketing segment. This is even the case for CX / KA code-share. However even if OP only has the "original" PNR, CX should be able to find the underlying code-share one if the agent is sophisticated enough. Might require HUACA.
