Route builder

Map airport codes into a shareable route list.

Paste IATA or ICAO codes like JFK, LHR, HND or one per line to plot a clean route preview, validate known airports, and export the result as JSON or CSV. This tool uses a curated major-airport directory, so unknown or regional airports may need manual checking.

Airport codes map generator

Codes are sanitized to letters only, converted to uppercase, and matched against the built-in directory. Route order follows the sequence you enter.

Separate entries with commas, spaces, arrows, or new lines. Duplicate codes are removed by default.
Options
Assumptions: map points use approximate latitude and longitude, route lines are straight projected segments, and distance is a rough great-circle estimate rounded to the nearest mile and kilometer.

How it works

1. Parse and sanitize

The tool splits your input on spaces, commas, arrows, and line breaks, strips non-letter characters, and uppercases the result so accidental punctuation does not break the route.

2. Match airports

Each token is checked against a curated airport directory using IATA codes first, then ICAO if enabled. Unknown entries are called out clearly instead of being ignored.

3. Draw and export

Matched airports are projected into an inline SVG map, route legs are totaled with a great-circle estimate, and the airport list can be copied or downloaded as structured output.

Planning note: this is a reference and formatting tool, not an operational aviation source. Always verify schedules, runway suitability, and current airport status with official aviation data before relying on a route.
