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

Sample CSV Output Format

PassengerName,PassengerID,FlightNumber
sam	23325	444
mary	4242	333
milly	3252	333
