Airline Analysis with Python and Flask, Aviationstack and Zenserp


Airline Analysis is fascinating. It’s where incredible engineering, complex logistics, and human stories meet 30,000 feet above the ground. But have you ever thought about how airlines create their routes and the stories those routes tell? In this blog, we’ll explore how to analyze airline routes, gather related news, show relevant images, and map these routes using Aviationstack, Python, Flask, and a bit of AI.

By the end of this blog, we’ll provide you with the code to:

  • Analyze airline routes using reliable data sources.
  • Collect and understand news about airlines.
  • Show relevant images to improve user understanding.
  • Map and explore these routes on a map.
  • Use AI, like OpenAI’s GPT-4, to create informative narratives about selected routes.
  • Use tools like requests, Plotly Express, Pandas, and Geopy for smooth functioning.
  • Create a user-friendly interface with Flask, accessible to everyone.

This blog aims to equip readers with the knowledge and code to build a platform that explains airline route networks and their stories. Whether you’re a data enthusiast, developer, or just curious about aviation, this blog will give you insights into data, visualization, and AI in airline analysis.

Our solution integrates a suite of specialized tools and APIs:

  • requests: Facilitates data retrieval from various APIs.
  • Plotly Express: Employs advanced graphics capabilities to visually represent airline routes on interactive maps.
  • Pandas: Provides robust capabilities for data manipulation and analysis.
  • Geopy: Converts city or airport names into precise geographical coordinates.
  • OpenAI: Uses the GPT-4 model to generate descriptive content related to airline routes and their narratives.

Flask as the Web Framework

Flask is our chosen lightweight web framework for Python. It supports the rapid development of this application, with a primary interface where users can view an airline’s routes, read about its history, and access the latest news and images.

Data Processing and Visualization

  • Data Retrieval: We utilize the aviationstack API, a rich source of information on airline routes, associated airports, and the types of aircraft in use.
  • AI-Powered Narratives: After processing the data, we employ OpenAI’s GPT-4 model. This offers users a detailed description of the airline’s history, its primary routes, and unique experiences.
  • Visualization: Plotly Express enables us to represent these routes on a map, with the Nominatim service from Geopy converting airport names to geographical coordinates for precision.

Updates on News and Images

We integrate the Zenserp API to continually update the application with:

  • News: The latest developments related to an airline, including new route launches or mergers.
  • Images: Visuals that showcase the branding and aesthetics of the airline’s fleet.

Interactivity and UI

The Flask-powered user interface boasts:

  • Dropdown Menu: Allows users to select from an extensive list of airlines.
  • Integrated Results: Displays visualized routes, narratives generated by GPT-4, current news, and related images upon selection.

Optimization Strategies

We have implemented certain best practices for efficiency:

  • Caching: We’ve incorporated a caching mechanism to reduce redundancy in geolocation queries.
  • Environment Variables for API Keys: API keys are sourced from environment variables for enhanced security and adaptability.

Deployment Overview with PythonAnywhere

Deploying our application is crucial to reach a global audience. To achieve this, we’ve chosen PythonAnywhere, an ideal platform for Python web applications.

Our application’s core lies in the union of flask_app.py and templates/airlines.html. The former manages data processes, API interactions, and routing, while the latter visualizes this data for users. This combination ensures the application is not only functional but also globally accessible. With this structure, we seamlessly bridge backend operations and frontend visuals, immersing users in the airline domain.

Key Aspects of the Deployment:

Deployment Platform

We’ve adopted PythonAnywhere, tailoring our application for global accessibility.

  • WSGI Configuration:
  • Adjusts system path to pinpoint project files.
    • Configures environment variables, enhancing security by preventing hardcoded sensitive data.
    • Prepares the Flask app to be the main touchpoint for web requests.
  • Flask Application Components:
  • flask_app.py: The Flask application’s nucleus. It oversees component management, routing, and user interfacing.
    • Sets up initial configurations, including necessary imports.
    • Carves out navigation paths, pinpointing the primary route.
    • templates/airlines.html: Steers the user interface and data portrayal.
      • Leverages Jinja2 for fluid data representation.
      • Incorporates interactive elements like maps and charts.
      • Facilitates user interactions through various UI elements

In essence, by harnessing Python, Flask, and PythonAnywhere, we’ve crafted a comprehensive tool for airline insights, enabling users to delve deeply into the world of aviation.
