But then QR274 got reinstated back to a similar late afternoon departure time from AMS. Your reservation for AMS to DOH got put back to this time.
But your DOH to BKK is still on the later retimed flight.

Just call up QR and either give them the details above, or just claim ignorance but ask to be put back on QR836 as you need to be in Bangkok for a meeting at 5pm. Assuming QR don't mess around with the operational plan QR836 is usually the A380, as opposed to QR832 which is usually a 777.
