+## About the Dataset
+
+This repository provides the OpenFlights database exported into **columnar Parquet format**, enabling efficient analysis, filtering, joins, and machine learning workflows.
+
+It is designed as a multi-configuration dataset, where each table is stored as its own configuration with a single split named `default`.
+
+Included data:
+
+- Airports (basic + extended metadata)
+- Airlines
+- Routes between airports
+- Aircraft models (planes)
+- Countries with ISO codes
+
+All Null/OpenFlights `\N` placeholders were converted to standard `NaN` values for clean schema typing.
+

+
+## Datasets Structure
+
+This dataset contains **6 subsets** :
+
+| Configurations | Description |
+|-----------|-------------|
+| `airports` | All known airport infrastructure worldwide |
+| `airports_extended` | Enhanced airport metadata (time zones, DST, categories, etc.) |
+| `airlines` | Commercial & private airlines with active status |
+| `routes` | Direct flight connections (airline + equipment info) |
+| `planes` | Aircraft types and codes |
+| `countries` | Country reference table (ISO 3166-1) |
+
+Note : Each configuration has a single split: `default`.
+
+Designed for relational joins using identifiers:
+
+- `airlines.AirlineID` ↔ `routes.AirlineID`
+- `airports.AirportID` ↔ `routes.SourceAirportID / DestinationAirportID`
+
+<p align="right">(<a href="#readme-top">back to top</a>)</p>
+
+## Schema
+
+### Airports
+
+- AirportID (int)
+- Name (string)
+- City (string)
+- Country (string)
+- IATA (string, nullable)
+- ICAO (string, nullable)
+- Latitude (float)
+- Longitude (float)
+- Altitude (int)
+- Timezone (float)
+- DST (string)
+- TzDBTimezone (string)
+
+### Airports Extended
+> Same columns as  `airports`, but typically higher data completeness and accuracy
+
+-   AirportID (int)
+-   Name (string)
+-   City (string)
+-   Country (string)
+-   IATA (string, nullable)
+-   ICAO (string, nullable)
+-   Latitude (float)
+-   Longitude (float)
+-   Altitude (int)
+-   Timezone (float)
+-   DST (string)
+-   TzDBTimezone (string)
+
+### Airlines
+
+- AirlineID (int)
+- Name (string)
+- Alias (string, nullable)
+- IATA (string, nullable)
+- ICAO (string, nullable)
+- Callsign (string, nullable)
+- Country (string, nullable)
+- Active (string: "Y" / "N")
+
+### Routes
+
+- Airline (string)
+- AirlineID (int, nullable)
+- SourceAirport (string)
+- SourceAirportID (int, nullable)
+- DestinationAirport (string)
+- DestinationAirportID (int, nullable)
+- Codeshare (string, nullable)
+- Stops (int)
+- Equipment (string)
+
+### Planes
+> Referenced in routes using Equipment codes.
+
+-   PlaneID (int)
+-   IATA (string, nullable)
+-   ICAO (string, nullable)
+-   Name (string)
+    
+
+Notes:
+-   Some aircraft may only have IATA or ICAO codes
+-   PlaneID is an OpenFlights internal identifier
+
+### Countries
+> Used as reference for airports and airlines
+
+-   Name (string)
+-   CountryCode (string, nullable - ISO 3166-1 format)
+
+Notes:
+-   Not all countries have official codes available
+-   Used for international standard alignment
+

+
+## Usage
+
+Load directly with 🤗 Datasets:
+
+```python
+from datasets import load_dataset
+
+airports = load_dataset("kylianmallet/openflights", name="airports").get("default")
+routes = load_dataset("kylianmallet/openflights", name="routes").get("default")
+
+print(airports.head())
+
+```
+
+Efficient joins using pandas / Polars / Apache Arrow:
+
+```python
+import polars as pl
+from datasets import load_dataset
+
+d_airlines = load_dataset("kylianmallet/openflights", name="airlines").get("default")
+d_routes = load_dataset("kylianmallet/openflights", name="routes").get("default")
+
+airlines = pl.from_arrow(d_airlines.data.table)
+routes = pl.from_arrow(d_routes.data.table)
+
+joined = routes.join(
+    airlines,
+    left_on="AirlineID",
+    right_on="AirlineID",
+    how="left"
+)
+
+print(joined.head())
+```
