Airport Codes

Fri Jan 20, 2006 12:21 pm


on most iata airport designations there is a fourth letter at the beginning of it [ex: iah/kiah]

what does this first letter mean? is it what country the airports in?

Its more so the region. Continental US airports start with K, but alaska and hawaii airports start with P. Great britain, the netherlands and germany all have airports starting with E.

Quoting Iah744 (Thread starter):
is it what country the airports in?

Exactly, the US is "K" and the UK is "EG", etc. That's basically it.

Check out this link, and the example for EGLL...


As another example, take Mexican airports. All start with "MM" and the 3rd and 4th characters define the specific airport, MMMX for Mexico City, MMUN for Cancun, etc.

I used to have a map from ICAO that showed all the general regions, as well as the individual countries, but I've long since misplaced it. It's probably available on the internet, somewhere...
