San Juan is TJSJ; other airports in Puerto Rico are going to start with TJ followed by the first two digits of their IATA code (e.g. SJ from SJU). From the main site (not the forums), you can click on “Don’t know the airport code?” on the left hand side and type in part of the airport name to get a list of options to click on. ---

Check the 3rd item in the posting at [discussions.flightaware.com/view … icao+codes](http://discussions.flightaware.com/viewtopic.php?t=252&highlight=country+icao+codes) This shows all of the ICAO codes. These form the 1st 2 letters of the airport code. If you notice, the USA actually has 7 different codes: K: 48 contiguous states PA: Alaska PB: Baker Island PG: Guam PH: Hawaii PJ: Johnston Island PW: Wake Island Baker Island’s airport is abandoned, Johnston Island’s airport is closed and not maintained, Midway has 3 airport but only one is operational, and Wake Island has 1 airport.
