Country ICAO codes

If you’ve ever wondered why Sydney Kingsford’s ICAO is YSSY and not KSSY, and why John F Kennedy Airport’s ICAO is KJFK and not YJFK, even if you haven’t wondered that, this chart will be interesting to you. I’ve had this for a couple months, but I thought of it again today.


ICAO is International Civil Avation Organization, in case you need to know.

Don’t get this confused with IATA, aka International Air Transport Association.


Very interesting! :)
