http://forum.geonames.org/gforum/posts/list/4.page JForum - http://www.jforum.net the IATA website there is airport codes and city codes. Fir example, try to find "STN" (location code for London Stansted Airport). You can see there is "STN" - airport code, but "LON" - city code. Now try to find "CHI" (city code for Chicago) and you will see many airports in Chicago. So IATA assigns TLAs not only to airports.]]> http://forum.geonames.org/gforum/posts/list/2836.page#9941 http://forum.geonames.org/gforum/posts/list/2836.page#9941 GMT http://forum.geonames.org/gforum/posts/list/2836.page#9951 http://forum.geonames.org/gforum/posts/list/2836.page#9951 GMT
