Offline airline directory

airlines.json is derived from the worldwide OpenFlights airline database, not a handpicked list of major carriers. It includes all 6,136 named entries with syntactically valid IATA or ICAO codes. Distinct record IDs preserve shared codes. The source's activity flag only affects search ordering: OpenFlights explicitly says it is unreliable. Historical airlines remain available for historical recordings. This snapshot cannot guarantee every current carrier.

Source and license: https://openflights.org/data.php (ODbL-1.0). The exact upstream revision, download SHA-256 and pinned source URL are in the JSON. airlines-LICENSE.txt contains the upstream database license. This separately licensed dataset is not covered by the recording archive's CC0 license or the app source's AGPL license.

To refresh, download data/airlines.dat at an exact OpenFlights revision, then run:

/home/sweisman/venv/bin/python analysis/tests/build_airline_directory.py /tmp/airlines.dat --revision UPSTREAM_COMMIT --output android/app/src/main/assets/airlines.json

Update the upstream license if needed and run FlightIdentityTest. Selection remains offline; valid carrier/number/date syntax is not historical flight verification. A later dated provider record must match the operating carrier, route and recording time before scientific use.
