body: <p>In new google map there are several travel mode like driving, bicycling, walking and transit but they also added fly mode also. I can choose fly mode in new google map but i cant get fly travel mode in google maps v3 api. I want to to show fly distance between two cities on my site like google map shows on google map.</p>

  <pre><code>$base_url = 'http://maps.googleapis.com/maps/api/directions/xml?sensor=false';
  $xml = simplexml_load_file("$base_url&amp;origin=Lahore&amp;destination=Multan");
  echo $distance = (string)$xml-&gt;route-&gt;leg-&gt;distance-&gt;text;
  echo $duration = (string)$xml-&gt;route-&gt;leg-&gt;duration-&gt;text
  </code></pre>
  
  <p>driving, walking and other modes are working but fly is not working.</p>
