About

A short history

AS Route Map started in 2014 as a small companion tool for AirlineSim — the browser-based airline management game. The idea was simple: the game tells you what to do, this map shows you where. Show a virtual airline's network on a real world map, make it easy to spot missing connections, plan new routes and find airports that fit a new base.

The original site (ASP Classic, MySQL, Google Maps) grew over the following years: a tutorial for new players, a directory of worlds and airlines, a heat map for choosing a starting airport, weekly statistics and a live view of the aircraft flying around the world. It ran on private hardware and was maintained in spare time until 2026.

This is the 2.0 rebuild. It serves the same purpose — a map-centric view of your AirlineSim world — on a modern, fully open-source stack: Django, MariaDB and a MapLibre GL map with OpenFreeMap tiles. The aircraft positions are computed in your browser from the flight schedules; the server stays thin. All data is refreshed on a regular schedule from AirlineSim's public pages, and the site only ever reads from the game — it never sends any action on your behalf.

Data sources

• AirlineSim (airlinesim.aero) — world, airport and airline data, flight schedules and statistics, from the game's public web pages and its v2 API. AirlineSim is a game; this site is an independent, unofficial companion tool — generously tolerated by the game's operators.
• OpenStreetMap contributors — the base map is rendered from OpenStreetMap data via OpenFreeMap tiles. © OpenStreetMap contributors.
• Timezone boundary polygons — the map's optional time-zone layer draws its boundaries from timezone-boundary-builder, release 2026d (14 September 2026). The output data of that project is licensed under the Open Data Commons Open Database License (ODbL) 1.0; it is itself assembled from OpenStreetMap boundary data and the timezone identifiers defined by the IANA timezone database, so the thanks is owed to the OpenStreetMap contributors and the timezone database maintainers as well. We take those zone shapes, simplify them, and stamp each one with its standard (non-daylight-saving) UTC offset. The file we ship stays under that same ODbL 1.0 rather than under this site's GPLv3 code licence. The layer also prints its own 2026d · 2026-09-14 date in its legend, because a static snapshot of something that keeps changing should say how old it is instead of passing itself off as current.
• Legacy AS Route Map (2014–2026) — historical statistics and the aircraft-type catalogue carried over from the original site.

The map interface is built with MapLibre GL JS, a FOSS mapping library.
