Flight Reservation System

This assignment is about creating a graphical user interface (GUI) for an airport reservation system using Java Swing. The GUI has various components such as labels, text fields, combo boxes, and sliders that allow users to input their flight details and preferences. Users can search for flights and view available itineraries.
