@AirPassRightsCA Air Canada did the same. Swapped aircraft for “maintenance/ safety reasons” and the said aircraft flew elsewhere and was in continuous service.
@BestBuyCanada 30-day exchange policy not honoured. Bought headphone a week ago as gift, item had defect, could not exchange unless I pay up because price has changed. Was told system won't allow an exchange and the store does not have to honour sale from another store.
