Source policy
Evidence hierarchy
We prefer primary airport, government and transport operator sources. On-site verification and moderated traveler observations can add context, with their limitations shown.
Changes and unavailable sources
Each airport fact shows what a link supports. A source returning 403 or timing out is marked for manual review, not erased or treated as a factual change. We do not bypass website access controls.
Corrections
Send a source link and a description of the discrepancy to [email protected]. We review corrections before publication.
