Also in regaurds to range, every ten or so years a few companies, Boeing being one of them , I believe, relases new "still air ranges" over routes, based on the prevailing winds in the in the past decade. Well one of these was release shortly before or after the MD-11 entered srvice. Well the distance from the US west coast to HOng Kong grew by over 300 miles, this hurt almost all long range airliners that were already past the design phase.
