Flight Deal Notifier is an automated Python project that helps you discover and receive notifications about affordable flight deals. It employs Object-Oriented Programming (OOP) principles, API integration, Google Sheets interaction, and automation to simplify the process of finding budget-friendly flights.

OOP Structure: The project is organized using Object-Oriented Programming, with separate classes for data management, flight searching, and notifications.

API Integration: It integrates with various flight search APIs to retrieve real-time pricing and destination data.

Google Sheets Usage: Flight Deal Notifier interacts with Google Sheets to fetch and update flight data, ensuring accuracy and freshness.

Automation: The system automatically searches for flight deals, updates missing information, and sends real-time notifications when enticing deals are discovered.

Data Management (OOP): The DataManager class fetches flight price data from an external source, like Google Sheets. This class ensures that the data remains accurate and up-to-date.

API Integration: The FlightSearch class integrates with flight search APIs to search for deals. It retrieves IATA codes for cities, checks flight availability, and compiles comprehensive flight information.

Google Sheets Interaction: If any city lacks an IATA code, FlightSearch updates it using API calls and stores it back in Google Sheets.

Automated Deal Hunting: Flight Deal Notifier automates the process of searching for flight deals. It calculates travel dates, initiates flight searches, and identifies the best-priced flights.

Instant Notifications: When a great deal matching or surpassing the lowest expected price is found, the NotificationManager sends an SMS notification, ensuring you're informed in real time.

To use this project, follow the setup instructions in the documentation. You'll need Python, API keys, and a few dependencies.
