To make sure, let me emphasise, I've always enjoyed flying with QR in the past. In November we flew to Athens and it was a wonderful flight. In September we went to Denmark and in August to Germany, very good flights. In May back to the US where the flights while long, were wonderful. It seems to me so far, unscientifically, the shorter the distance, the "rougher" the ride. Possibly due to less experienced crew working shorter routes.
