# DelayGuard

> AI-powered US domestic flight delay predictor. Predicts delay probability for any US domestic flight using machine learning trained on 20M+ BTS records, live NOAA weather, and FAA advisory data.

## What DelayGuard does

- Predicts flight delay probability (0-100%) for US domestic routes
- Covers all major US airlines: American, Delta, United, Southwest, JetBlue, Alaska, Frontier, Allegiant, Hawaiian, Sun Country
- Covers 22 major US airports with detailed delay risk profiles
- Provides real-time weather, FAA Ground Delay Program, and NAS congestion signals
- Tracks SpaceX launch scrub probability using NASA Launch Commit Criteria and live weather

## Data sources

- Bureau of Transportation Statistics (BTS) on-time performance data: 2023-2025 (20M+ flights)
- NOAA Aviation Weather Center: live METARs, TAFs, PIREPs, SIGMETs
- FAA: NOTAM data, Ground Delay Programs, Ground Stops
- OpenWeatherMap: 5-day 3-hourly forecast
- Open-Meteo: 16-day hourly forecast
- AviationStack: live flight status (FlightAware fallback)

## Model

- XGBoost classifier (v9), 155 features
- Trained on 36 months of US domestic flight data
- Features include: route history, tail number history, weather severity, FAA NAS status, time-of-day, day-of-week, carrier performance

## Accuracy

- Overall delay rate in training data: ~20.9%
- Model covers all major US hub-to-hub routes
- Live data gate: METAR/NOAA/FAA only applied within 6 hours of departure
