Why are Alaska and Hawaii ICAO airport codes different from those in the contintental U.S.?

Wed May 13, 2020 11:32 pm

I have noticed a while ago that airports in Alaska and Hawaii have their ICAO codes start with "P" instead of "K", as in the rest of the U.S.. For example; Anchorage is PANC instead of KANC. Is there a specific reason for this?

The ICAO system was devised before either were states and both were assigned to the PAC ICAO region.

Because they are not in the continental United States.

Alaska and Hawaii gained statehood under the US Constitution in 1959 - long after the initial ICAO "K" codes were compiled for the continental USA.

Let's not forget that when the ICAO proposed four-letter codes in 1947, the USA objected and said three-letter codes were sufficient...

Indeed, the very first proposal was [national identification][specific airport], each of two letters.

Today's IATA (International Air Transport Association) i.e. travel agencies, use a similar system. KJK (ICAO) = JFK (IATA); EGKK (ICAO) - LGW (London, Gatwick, IATA), etc.

Hope that helps the understanding.
