I believe that the "K" is only supposed to be used for International
Airports. I wonder how the good old USA got a "K" when Canada got a "C"
and Great Britain got a "G"? When we stay within our boundries, we don't
need a letter to tell us that we are navigating within our own country.

The USA (and most countries) got an ICAO airport letter to match that
country's main ITU radio callsign prefix. Since Kxx is allocated for
USA radios, our airports got the "K".
