Flight Delay Prediction System - Premium Flask Application

🚀 Complete Migration: Streamlit → Flask

📋 Project Overview

A comprehensive flight delay prediction system with modern glassmorphism design, real-time analytics, and machine learning integration.

🎯 Key Features

  • ✅ Real-time flight delay predictions with ML model integration
  • ✅ Interactive dashboard with 6 different chart types
  • ✅ Comprehensive form with all airlines and airports
  • ✅ Premium glassmorphism design with airport background
  • ✅ Responsive design for all screen sizes
  • ✅ Real-time updates and live status monitoring

🏗️ Architecture

Backend (Flask)

  • RESTful API endpoints for predictions and data
  • Dynamic data loading from CSV files
  • Machine learning integration with fallback logic
  • JSON responses for frontend integration

Frontend (HTML/CSS/JavaScript)

  • Modern glassmorphism design with backdrop blur
  • Chart.js integration for beautiful visualizations
  • Real-time updates every 5 seconds
  • Smooth animations and micro-interactions

📊 Charts & Analytics

  1. Hourly Delay Patterns - Bar chart showing delays by hour
  2. Seasonal Breakdown - Pie chart with seasonal trends
  3. Feature Importance - Horizontal bar chart
  4. Prediction Trends - Line chart over time
  5. Airline Performance - Compare delay rates by airline
  6. Airport Performance - Dual-axis chart with volumes and delays

✈️ Data Sources

  • Airlines: All major Indian and international carriers
  • Airports: 20+ major airports (DEL, BOM, BLR, JFK, LAX, etc.)
  • Flight Data: Historical flight patterns and delays
  • Weather Integration: Real-time weather conditions

🎨 Design System

  • Background: Custom airport terminal image with parallax effect
  • Color Palette: #2F80ED (Primary), #0B2A4A (Navy), #27AE60 (Green)
  • Typography: Inter font family for modern readability
  • Cards: Glassmorphism with backdrop blur and soft shadows
  • Animations: Smooth transitions and hover effects

🔧 Technical Stack

  • Backend: Flask 2.3.3 with Python
  • Frontend: HTML5, CSS3, JavaScript ES6
  • Charts: Chart.js for responsive visualizations
  • Styling: Custom CSS with glassmorphism effects
  • Data: Pandas, NumPy for processing
  • ML: Scikit-learn with joblib model persistence
