I advise that all money conversations between you and the AA RTW desk be in regard to Jordanian currency.
At the point of actual purchase ---- when presumably there are no remaining disagreements/misunderstandings regarding the all-in JD total ---- should the all-in total of JD be converted into Canadian dollars.
Are you unable to price the itinerary (and all taxes) in JD on the OW Tool? ime, the only discrepancy should be the YQ (and AA will hopefully be charging significantly less YQ than BA or whatever other airline the tool assigns to price the online ticket....)
