Flight Booking Management System

A terminal-based Python application for managing flight customers, destinations, bookings, optional services, and membership discounts. Data is stored in plain-text, comma-separated files, so the project runs without a database or third-party packages.

Features

• Create bookings for registered customers
• Register standard, member, and VIP customers
• Apply member and threshold-based VIP discounts
• Add destinations and track available seats
• Attach individual services or service bundles to a booking
• List customers, destinations, services, bundles, and bookings
• Report the most valuable customer and most popular destination
• Load a different set of data files from command-line arguments

Requirements

• Python 3
• A terminal that supports interactive input

The application uses only the Python standard library.

Run the sample application

Clone the repository and start the menu from its root directory:

git clone https://github.com/SIBTAIN-ASAD/Flight-MS-Python.git
cd Flight-MS-Python
python3 code.py

The included sample data is loaded from:

• customers.txt
• destinations.txt
• services.txt
• bookings.txt

Some menu actions append records to these files. If you want to preserve the sample data, work on copies and pass their paths explicitly:

mkdir -p /tmp/flight-ms-demo
cp customers.txt destinations.txt services.txt bookings.txt /tmp/flight-ms-demo/
python3 code.py \
  /tmp/flight-ms-demo/customers.txt \
  /tmp/flight-ms-demo/destinations.txt \
  /tmp/flight-ms-demo/services.txt \
  /tmp/flight-ms-demo/bookings.txt

The four file arguments must be supplied in this order: customers, destinations, services, and bookings. If no arguments are supplied, the files in the current directory are used.

Menu

The interactive menu can:

1. Book a trip
2. Display customers
3. Display destinations
4. Add a customer
5. Add a destination
6. Display bookings
7. Display services and bundles
8. Display the most valuable customer
9. Display the most popular destination

Enter q to exit.

Data model

The implementation is organized around a small set of classes in code.py:

Class	Responsibility
Customer, Member, VIPMember	Customer identity, value, membership, and discount rules
Destination	Ticket price and available seats
Service, Bundle	Optional booking services
Booking	Customer, destination, service, discount, and date for one trip
Records	File loading, lookup, storage, and aggregate reports
MenuDriverClass	Interactive menu and booking workflow

Customer IDs use C, M, or V prefixes for standard customers, members, and VIP members. Destination, service, and bundle IDs use D, S, and B prefixes respectively.

Data files

Each record is comma-separated. For example:

# customers.txt
C1, James, 0, 100
M3, Tom, 0.1, 500

# destinations.txt
D1, Sydney, 150, 30

# services.txt
S1, Internet, 0
B8, StarterMax, S1, S2, S3, S4

# bookings.txt
James, D1, 1, S1, 0, 12/12/2021 12:12:12

Validation

Check that the source parses without running the interactive menu:

python3 -m py_compile code.py

Project scope

This project was built as a programming-fundamentals exercise. It favors a single-file, object-oriented implementation and text-file persistence so the customer, booking, inheritance, and menu workflows remain easy to inspect.
