Overview:

The Airline Delay Prediction System is a Machine Learning–based project that predicts whether a flight will be on-time or delayed based on various historical and real-time factors such as weather conditions, flight schedule, route, air traffic, and airline performance.

Flight delays are a major challenge in the aviation industry, affecting passengers, airlines, and airports. This system helps to analyze flight patterns, identify causes of delay, and predict delays in advance to minimize disruption.

By applying data analysis and machine learning algorithms, the system can make accurate predictions to help airlines optimize operations and passengers plan better.

Objectives:

• To analyze historical flight data and identify key factors causing delays.

• To train machine learning models that predict if a flight will be delayed.

• To provide an accurate and real-time delay prediction system.

• To assist airlines in improving scheduling efficiency and reducing losses.

Key Features:

1. Machine Learning Prediction: Predicts if a flight will be delayed or on-time.

2. Flight Data Analysis: Uses data like airline, route, distance, departure/arrival time, and weather.

3. Weather Integration: Considers temperature, wind, and precipitation in delay prediction.

4. Data Visualization: Displays trends, delay statistics, and prediction accuracy using charts.

5. Model Comparison: Compares algorithms like Decision Tree, Random Forest, Logistic Regression, and XGBoost.

6. Flight Data Storage: Maintains historical records for model training.

7. User Dashboard: Allows users or airline staff to check predicted flight status easily.

Tech Stack:

Frontend:

• HTML, CSS, JavaScript, Bootstrap (for dashboard and visualization)

Backend:

• Python (Flask or Django framework)

Machine Learning Libraries:

• Pandas, NumPy, Scikit-learn, Matplotlib, Seaborn

• XGBoost / LightGBM (for high-accuracy classification)

Database:

• MySQL / MongoDB

Optional APIs:

• OpenWeatherMap API (for weather data)

• FAA or aviation dataset (for real flight delay data)

System Workflow:

1. Data Collection:
   Collects flight data such as flight number, airline, departure and arrival airports, weather conditions, and historical delays.

2. Data Preprocessing:

   • Cleans and normalizes data.

   • Handles missing values and encodes categorical features (like airline or airport).

3. Feature Selection:
   Identifies key attributes that influence delays — e.g., departure time, route, airline, weather conditions.

4. Model Training:
   Trains multiple machine learning models using labeled datasets (On-time / Delayed).

5. Prediction:
   The trained model predicts whether a given flight is likely to be delayed or on time.

6. Visualization:
   Dashboard shows flight trends, delay causes, and prediction probability.

Example Use Case:

A user enters flight details such as:

• Airline: Indigo

• Departure: Mumbai

• Arrival: Delhi

• Scheduled Time: 09:00 AM

• Weather: Cloudy

The system processes this data and predicts:

“This flight has a 78% probability of being delayed by 15 minutes or more.”

It also displays charts showing delay trends for that route and airline.

Applications:

• Airlines: Improve schedule planning and reduce delays.

• Passengers: Get early information about expected delays.

• Airports: Manage gate and runway allocations efficiently.

• Data Analysts: Study flight performance and delay trends.

• AI Research: Develop predictive models for logistics and transportation.

Future Enhancements:

• Integration with real-time flight tracking systems (ADS-B or FlightRadar24 API).

• Use of Deep Learning (LSTM) for time-series delay prediction.

• Inclusion of air traffic and maintenance data for higher accuracy.

• Develop mobile app interface for quick delay notifications.

• Add NLP-based chatbot for passengers to query flight status.
