You didn't specify which Mastercard and which country's Amex. Amex Membership Rewards is a bit different in each Amex issuing country. But on both cards, if QR, BA, or IB are transfer partners then you're golden. They all share Avios as a common currency and you can shift the points between them quite easily.
