Bean counters are pushing A380 to JNB and B787 to Santiago. The B787 is unsuitable for JNB. If the A380 approval does not get the thumbs up, I wouldn’t be surprised if a few 744ER’s are retained for this roll(no need to update, no competition), or the destination will be dropped, due lack of a suitable aircraft, and code share used, ie EK via Dubai, dispite how distasteful the travel time would be, to the seasoned traveler.
