This and its long range (8000km for -200 &amp;amp; 6800km for -300) and its 3 hours ETOPS capability makes it a very versatile aircraft. So it is widely accepted in USA, as well as less developed places China, Africa, and Iceland, which has harsh climate &amp;amp; air traffic insufficient to support widebody operations. It is also widely accepted by many charter airlines.&lt;br /&gt;&lt;br /&gt;But its narrowbody design makes its sales poor in Asia except China, because most Asians prefer taking more comfortable widebodies of similar capacity as B757 like B767, A310 &amp;amp; A300.&lt;br /&gt;&lt;br /&gt;If B757 is improved further so it has 10000km range, then there would be more non-stop air service not sufficient to support widebody operation, thus making B757 more popular.&lt;br /&gt;&lt;br /&gt;How good it will be if Airbus produces A322 &amp;amp; A323 competiting B757-200 &amp;amp; -300 with more range &amp;amp; more commonality, so airlines can operate more point to point routes not sufficient to support widebody operation, while they can reduce flight crew training &amp;amp; maintenance cost compared to B757.</description></item></channel></rss>
