Code:

public class FlightReservationMain extends JPanel {
    FlightReservationMain enclosingClassRef = this;
    private static JTable jTable;
    private JButton jButton5;

public FlightReservationMain() {
    jButton5 = new JButton("Search");
    jButton5.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            SearchFlight search = new SearchFlight();
            // call methods/access fields in search...
            // If the SearchFlight class needs a reference to this
            // enclosing class, viz, FlightReservationMain, you can
            // send a reference to it via a (new) constructor:
            SearchFlight search = new SearchFlight(enclosingClassRef);
            // Or if SearchFlight needs only a reference to the table
            // you can send a reference to it along in a constructor:
            SearchFlight search = new SearchFlight(jTable);
            // or perhaps in a method:
            search.setTable(jTable);
        }
    });
