Display labels only to specific cities in Google Maps

Question

I have polylines connecting two points on the map. I want to display labels only for those two points, and hide all other labels.

I have explored the Google Maps A

Example from Google maps hide smaller cities (localites) with your code/polylines:

function initialize() {
  var MY_MAPTYPE_ID = 'custom_style';
  //var MY_MAPTYPE_ID = google.maps.MapTypeId.ROADMAP;
  var featureOpts = [{
    stylers: [
      //     { hue: '#890000' },
      {
        visibility: 'on'
      }
    ]
  }, {
    elementType: 'labels',
    stylers: [{
      visibility: 'off'
    }]
  }, {
    featureType: "administrative.country",
    elementType: "labels",
    stylers: [{
      visibility: "off"
    }]
  }, {
    featureType: "administrative.locality",
    elementType: "labels",
    stylers: [{
      visibility: "off"
    }]
  }, {
    featureType: 'road',
    stylers: [{
      color: '#00FF00'
    }, {
      visibility: 'off'
    }]
  }];


  var mapOptions = {
    zoom: 3,
    center: new google.maps.LatLng(0, -180),
    mapTypeControlOptions: {
      mapTypeIds: [google.maps.MapTypeId.TERRAIN, MY_MAPTYPE_ID]
    },
    mapTypeId: MY_MAPTYPE_ID
  };

  var map = new google.maps.Map(document.getElementById('map-canvas'),
    mapOptions);

  var styledMapOptions = {
    name: 'Custom Style'
  };

  var flightPlanCoordinates = [
    new google.maps.LatLng(40.7127, -74.0059),
    new google.maps.LatLng(-27.46758, 153.027892)
  ];
  var flightPlanCoordinates1 = [
    new google.maps.LatLng(50.7127, -74.0059),
    new google.maps.LatLng(-27.46758, 153.027892)
  ];

  var flightArray = [];
  flightArray.push(flightPlanCoordinates);
  flightArray.push(flightPlanCoordinates1);

  var colorArray = [];
  colorArray.push('#FF0000');
  colorArray.push('#00FF00');


  // Code for displaying the polylines in the browser
  for (var i = 0; i < flightArray.length; i++) {

    var flightPath = new google.maps.Polyline({
      path: flightArray[i],
      geodesic: true,
      strokeColor: colorArray[i],
      strokeOpacity: 1.0,
      strokeWeight: 1
    });
    var customMapType = new google.maps.StyledMapType(featureOpts, styledMapOptions);
    map.mapTypes.set(MY_MAPTYPE_ID, customMapType);
    flightPath.setMap(map);
  }
  var citiesJSON = {
    geonames: [{
      lat: 40.7127,
      lng: -74.0059,
      name: "New York"
    }, {
      lat: -27.46758,
      lng: 153.027892,
      name: "Brisbane"
    }, {
      lat: 50.7127,
      lng: -74.0059,
      name: "Quebec"
    }]
  };
  var mapLabels = [];
  for (var i = 0; i < citiesJSON.geonames.length; i++) {
    var myOptions = {
      content: citiesJSON.geonames[i].name,
      boxStyle: {
        border: "none",
        textAlign: "center",
        fontSize: "8pt",
        width: "100px"
      },
      disableAutoPan: true,
      pixelOffset: new google.maps.Size(-50, 0),
      position: new google.maps.LatLng(citiesJSON.geonames[i].lat,
        citiesJSON.geonames[i].lng),
      closeBoxURL: "",
      isHidden: false,
      pane: "mapPane",
      enableEventPropagation: true
    };

    var ibLabel = new InfoBox(myOptions);
    ibLabel.open(map);
    mapLabels.push(ibLabel);
    var marker = new google.maps.Marker({
      position: new google.maps.LatLng(citiesJSON.geonames[i].lat,
        citiesJSON.geonames[i].lng),
      map: map,
      icon: {
        path: google.maps.SymbolPath.CIRCLE,
        scale: 2
      }
    });
  }
}

google.maps.event.addDomListener(window, 'load', initialize);
