I thought of 4 immediate classes:-
---------------------------------

public class AirPlane
{
    // Attributes
    public Integer plane_ID;
    public String airLine;
	
	//some getter,setter
}

public class Flight
{
    // Attributes
       private Integer flight_ID;
       private String from_location;
       private String to_location;
       private TimeStamp departureTime;
       private TimeStamp arrivalTime;
       private String description;
       private Integer plane_FKey; //mapped to plane_ID

    // Operations
    public  TimeStamp getArrivalTime()   {...}
    public  TimeStamp getDepartureTime()  {...}
}


public class Arrivals
{
    // Attributes
    private List<Flight> arrivingFlights;
   
    // Operations
    private  void displayFlights()  {...}
} 

public class Departures
{
    // Attributes
    private List<Flight> departingFlights;
   
    // Operations
    private  void displayFlights()  {...}
}

Who produces the arriving . departure feed ?
Feed pushed to a MQ or what?
Then who has responsibility to consume MQ messeges? What are next classes till updation of display board ?
Any Controller or Manager class - like DashBoard / DashboardController / FlightMonitorController ? What will be their responsibilities ?
What else I'm missing and what correction needed more ?
