var infowindow = new google.maps.InfoWindow(

Solution

Display an infowindow by getting the coordinate of the first point in the path of the polygon and using it for the infowindow

google.maps.event.addListener(flightPath,'click', function() {

   infowindow.setPosition(this.getPath().getAt(0));
   infowindow.open(map);
 });

OTHER TIPS

google.maps.event.addListener(flightPath,'click', function() {
    var aar=this.getPaths();

    infowindow.setPosition(arr.getAt(2));
    infowindow.open(map,flightPath);
 });
