I wonder if our September trip has any bearing on this topic. We were scheduled to fly DOH - JNB (Johannesburg) in 777 (Q Suites) and this has been the case since the trip was booked 2 months ago. Yesterday, it was changed to Airbus 350-1000 (Q Suites). While we are always expecting aircraft swaps on QR, this change may mean more Airbus 350s will become available.
