# Pro Flight Search — full LLM & data map

> Live flight-disruption intelligence across 200+ airports: delays, weather-delay risk, and open downloads. Free to cite with attribution (CC BY 4.0). Figures are independent travel-intelligence signals, not official airport or airline operational data.

## How to consume
- **Browsers** get HTML at the canonical URLs below.
- **Markdown twins** for answer engines: append `.md` to the path (e.g. `/global-airport-delays.md`) or send `Accept: text/markdown`, or add `?format=md` / `?format=markdown` on the HTML URL.
- **Raw data**: `/data/airport-delays.json` and `/data/airport-delays.csv` (airport delay snapshot). `Content-Type` JSON or CSV; `Access-Control-Allow-Origin: *`.
- **Sitemap**: https://proflightsearch.com/sitemap.xml (index of section sitemaps).

## Update cadence
- Global delays, weather-risk, worst-airports ranking: **hourly** (AeroDataBox delay windows + AVWX refresh).
- Airtime recovery snapshot: **every 6 hours when stale** (ClickHouse paired-leg rollup).
- Open-data JSON/CSV: same generation stamp as the global delay dashboard (`generated_at` field).

## Airport delay snapshot — data dictionary (JSON/CSV columns)
| Column | Meaning |
|--------|---------|
| iata | Airport IATA code |
| city | City name from Pro Flight Search catalog |
| country | ISO 3166-1 alpha-2 country code (e.g. US, GB, CI) |
| delay_index_arr | Arrival delay index (higher = more arrival delay pressure) |
| delay_index_dep | Departure delay index |
| delay_avg_arr_min | Median arrival delay in minutes |
| delay_avg_dep_min | Median departure delay in minutes |
| arr_canceled | Arrivals canceled today (airport tally) |
| dep_canceled | Departures canceled today |
| recorded_at | ISO timestamp of the upstream delay window |

On-time / delayed flight counts are **not** emitted — the live feed does not populate them reliably.
