Commercial flight logbooks frequently lock historical travel records behind annual subscriptions or shut down unexpectedly, whereas AirTrail preserves your complete aviation history on an interactive world map under your own control. Enter a flight number to look up routes automatically or log departures manually with seat numbers, cabin classes, aircraft registrations, timestamps, notes, and custom metadata fields. Switching from another tracker takes seconds: the built-in importer ingests CSV, ICS, and JSON exports from MyFlightradar24, Flighty, App in the Air, OpenFlights, TripIt, JetLog, byAir, and JetLovers. The vector map renders geodesic flight paths, recorded GPS tracks, and airport runway details across customizable basemaps. Detailed statistics dashboards break down total distance flown, time in the air, top airlines, aircraft models, and visited countries. Families and travel groups can share a single instance with role-based permissions, OAuth single sign-on, and read-only public links, while developers automate entries through the versioned REST API or Model Context Protocol server.
