How to make amcharts 5 flight from source to destination only

I have a requirement for the amcharts 5 map to show plane fly from the source (Paris) to the destination (LA) only and not turn around and fly back as it does for the demo map from amcharts.

Does anyone know how this would be achieved or should I be using another animation?

// Create root element
// https://www.amcharts.com/docs/v5/getting-started/#Root_element
var root = am5.Root.new("chartdiv");

// Set themes
// https://www.amcharts.com/docs/v5/concepts/themes/
root.setThemes([
  am5themes_Animated.new(root)
]);

// Create the map chart
// https://www.amcharts.com/docs/v5/charts/map-chart/
var chart = root.container.children.push(am5map.MapChart.new(root, {
  panX: "rotateX",
  panY: "translateY",
  projection: am5map.geoMercator(),
  homeGeoPoint: { latitude: 2, longitude: 2 }
}));

var cont = chart.children.push(am5.Container.new(root, {
  layout: root.horizontalLayout,
  x: 20,
  y: 40
}));

// Create series for background fill
// https://www.amcharts.com/docs/v5/charts/map-chart/map-polygon-series/#Background_polygon
var backgroundSeries = chart.series.push(am5map.MapPolygonSeries.new(root, {}));
backgroundSeries.mapPolygons.template.setAll({
  fill: root.interfaceColors.get("alternativeBackground"),
  fillOpacity: 0,
  strokeOpacity: 0
});

// Add background polygon
// https://www.amcharts.com/docs/v5/charts/map-chart/map-polygon-series/#Background_polygon
backgroundSeries.data.push({
  geometry: am5map.getGeoRectangle(90, 180, -90, -180)
});

// Create main polygon series for countries
// https://www.amcharts.com/docs/v5/charts/map-chart/map-polygon-series/
var polygonSeries = chart.series.push(am5map.MapPolygonSeries.new(root, {
  geoJSON: am5geodata_worldLow
}));

// Create line series for trajectory lines
// https://www.amcharts.com/docs/v5/charts/map-chart/map-line-series/
var lineSeries = chart.series.push(am5map.MapLineSeries.new(root, {}));
lineSeries.mapLines.template.setAll({
  stroke: root.interfaceColors.get("alternativeBackground"),
  strokeOpacity: 0.3
});

// Create point series for markers
// https://www.amcharts.com/docs/v5/charts/map-chart/map-point-series/
var pointSeries = chart.series.push(am5map.MapPointSeries.new(root, {}));

pointSeries.bullets.push(function() {
  var circle = am5.Circle.new(root, {
    radius: 7,
    cursorOverStyle: "pointer",
    tooltipY: 0,
    fill: am5.color(0xffba00),
    stroke: root.interfaceColors.get("background"),
    strokeWidth: 2,
    draggable: false
  });

  return am5.Bullet.new(root, {
    sprite: circle
  });
});

var paris = addCity({ latitude: 48.8567, longitude: 2.351 }, "Paris");
var la = addCity({ latitude: 34.3, longitude: -118.15 }, "Los Angeles");

var lineDataItem = lineSeries.pushDataItem({
  pointsToConnect: [paris, la]
});

var plane = am5.Graphics.new(root, {
  svgPath:
    "m2,106h28l24,30h72l-44,-133h35l80,132h98c21,0 21,34 0,34l-98,0 -80,134h-35l43,-133h-71l-24,30h-28l15,-47",
  scale: 0.06,
  centerY: am5.p50,
  centerX: am5.p50,
  fill: am5.color(0x000000)
});

planeSeries.bullets.push(function() {
  var container = am5.Container.new(root, {});
  container.children.push(plane);
  return am5.Bullet.new(root, { sprite: container });
});

var planeDataItem = planeSeries.pushDataItem({
  lineDataItem: lineDataItem,
  positionOnLine: 0,
  autoRotate: true
});

planeDataItem.animate({
  key: "positionOnLine",
  to: 1,
  duration: 10000,
  loops: Infinity,
  easing: am5.ease.yoyo(am5.ease.linear)
});

planeDataItem.on("positionOnLine", function(value) {
  if (value >= 0.99) {
    plane.set("rotation", 180);
  } else if (value <= 0.01) {
    plane.set("rotation", 0);
  }
});

function addCity(coords, title) {
  return pointSeries.pushDataItem({
    latitude: coords.latitude,
    longitude: coords.longitude
  });
}

// Make stuff animate on load
chart.appear(1000, 100);
