Emirates' CEO said early this year or late last year that A350 and 787 don't satisfy his company's needs/desires. He has said what he wants is a 787-9 that seats 290 passengers in a three class layout. Presumably he wanted the 787-9's range as well. In other words he wanted a A345 replacement. Looking at range maps for the various A350 and 787 models flying out of DXB, it's readily apparent that the proposed A359's range would not allow EK to fly to every point on the populated continents and wealthy island nations, whereas the A358, 788, and 789 would allow them to do so. Is EK looking for the last plane model they will ever need in 280-300 pax market, one that will allow them to cheaply (due to low acquisition and operation costs) reach any place in the world that has enough paying customers to make the trip worthwhile?
