Okay, hi all, I was wondering about the odd designators for ICAO airport codes. Could anyone please explain how, the US for example got K as the first letter for its codes,. E.g. KJFK for JFK. KBOS for BOS and so on.
I know that regions or "zones" have a basic First letter, like Southern and Central Africa has F as its preceding letter, or W for Southeastern Asia.
Was it just a random draw initially or was there any specific rhyme or reason to it?
