JavaBean,

Thanks for the tip. I've added in an ArrayList and added code so I can see the output after each entry asking for the size of the ArrayList and the contents of it. Each time I add data I keep getting a size of 1 and only the most recent element. It is the same even if I call to a particular index value. I also tried specifing the capacity of the array and still the same result. Any thoughts on what 'm doing wrong?

Code:

import java.util.ArrayList;

public class FlightInterface implements ActionListener {
    JButton exitButton;
    JButton getDataButton;

    JTextField nameInputField;

    ArrayList<String> airlineArray;
