[SOLVED] JGraphT graph shortest path

I am trying to calculate the total cost of the shortest path for a flight itinerary system, but it seems to be calculate the number of paths it take instead of the length/cost. I am unable to workout how to get the cost for each journey from the Flight_Info object.

Here is my code:

import java.util.Scanner;
import org.jgrapht.graph.*;
import org.jgrapht.Graphs;
import org.jgrapht.alg.DijkstraShortestPath;

public class Flights2 {

public static SimpleDirectedWeightedGraph<String, Flight_Info> createGraph() {

    SimpleDirectedWeightedGraph<String, Flight_Info> airport = new SimpleDirectedWeightedGraph<String, Flight_Info>(
            Flight_Info.class);

    String Edinburgh = new String("Edinburgh");
    String Heathrow = new String("Heathrow");
    String Dubai = new String("Dubai");
    String Sydney = new String("Sydney");
    String KualaLumpur = new String("Kuala Lumpur");
    String Frankfurt = new String("Frankfurt");
    String Aukland = new String("Aukland");
    String RioDeJanerio = new String("Rio De Janerio");
    String NewYork = new String("New York");
    String Santiago = new String("Santiago");

    airport.addVertex(Edinburgh);
    airport.addVertex(Heathrow);
    airport.addVertex(Dubai);
    airport.addVertex(Sydney);
    airport.addVertex(KualaLumpur);
    airport.addVertex(Frankfurt);
    airport.addVertex(Aukland);
    airport.addVertex(RioDeJanerio);
    airport.addVertex(NewYork);
    airport.addVertex(Santiago);
