## 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`

## 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())
```
