Flight Booking System (C++)

This project is a console-based flight booking system implemented in C++ using object-oriented programming. It allows users to add flights, book tickets for passengers, list current bookings, and export booking data to a CSV file for persistence.

Features

• Add new flights with a unique flight number and seat capacity
• Book flights for passengers with automatic seat availability check
• List all existing bookings
• Export booking data to a CSV file (bookings.csv)
• Automatically reload bookings from the CSV file (if present) on startup

Classes

Passenger

Represents a passenger with:

• name
• id

Includes methods for:

• Converting to/from CSV strings

Flight

Represents a flight with:

• flightNumber
• seats (total capacity)
• booked (seats already booked)

Includes:

• Seat availability checks
• Booking a seat
• Conversion to CSV format

Booking

Handles:

• Booking logic
• Flight and passenger storage
• CSV file export and import
• In-memory management using vector

How It Works

When the program starts, it:

• Loads previous bookings (if bookings.csv exists)
• Adds some sample flights
• Prompts the user with a menu to:
  1. Add a new flight
  2. Book a flight for a passenger
  3. Display all bookings
  4. Export to CSV
  5. Exit
