I have made a tactical error in that I credited my wife's March NZ flights to her newly created NZ AP account thinking it would be better than accruing to AC's Aeroplan.
In hindsight looking at the AC travel she has done since March and more AC travel booked for June/July, she will have a decent shot at making AC 50K which gives *G.

In order to achieve this I need to have her March AP returned to NZ so that I can then have Aeroplan claim them.

Has anyone had any success getting this done and what does one ask for? Is there a technical or industry name for the request?

TIA
