Last September when I went to Zambia, the Qatar flight from DOA to JNB was the old Business class seat, and thats what showed on my Itinerary . My return from JNB was suppose with be on a Qsuite as shown on my Itinerary. While hunting I received a message that my return flight from JNB was cancelled, then another that I had been rescheduled to another flight. Same flight times, same number, but no Qsuite, regular business class. One would think they could have just sent a notice of change of equipment and seat.
