The world of airport codes is a wonder and a mystery. As we discussed in episode 004 of the podcast, their origins can be found in meteorological stations, regulations, old city names or airfield names.
For the wonder, head to AirportCod.es, such a glorious website. An image is worth a thousand, well, airport codes:
If your airport of choice is not listed, you can simply tweet the authors and they'll add it. For those geeks of you (no, not the avgeeks, the tech geeks), you can contribute to the code that powers the website over at its GitHub repository.
With that sense of wonder and parts of the mystery removed (only parts, as the real discovery remains in visiting those airports!), they'll become your building blocks to start playing with ITA Matrix.
