An airline booking system streamlines the process of booking flights, managing passenger information, and handling reservations efficiently. This system allows customers to easily book flights and select their preferred seats. Airline staff can use the system to keep track of bookings and manage passenger lists. Utilizing advanced programming concepts, this system ensures a seamless and hassle$-$free travel experience for both passengers and airline personnel.

The system is structured around key classes such as Flight, which stores flight$-$specific details like flight number, departure and arrival locations, and seats; Passenger, which maintains essential passenger details like name and passport number; and Ticket, which manages booking information including flight, passenger, seat number, and class $($economy$,$ business, etc.$).$ The system also features comprehensive file I$/$O operations to read flight and passenger data from input files and write booking confirmations and ticket details to output files. Advanced programming techniques are used to manage seat availability using a two$-$dimensional array and implement various methods for booking operations. These include searching for flights, booking and canceling tickets, and viewing all available flights and specific ticket details, ensuring an efficient and user$-$friendly airline booking experience.

Step $1$: Registering Passenger and Flight Details

Before initiating the booking process, the Airline Ticket Reservation System requires the

registration of passengers and flight details. This foundational step ensures that all necessary data is available for efficient ticketing and flight management. The system introduces the AddPassenger command, enabling the addition of passenger details. Each passenger is uniquely identified by their passport number and associated with a name. Subsequently, the AddFlight command is introduced to register flight details. Each flight is identified by a unique flight number and includes essential information such as the departure and arrival cities, gate number, and a two$-$dimensional array representing seat assignments. The array links each seat to a passenger's passport number, allowing for precise seat allocation. Additionally, flight details encompass the class of the ticket $($Economy$,$ Business, or First Class$)$ and a unique reservation confirmation number, pivotal for tracking and managing bookings.
