So what airport codes are you dealing with

KMCI - Mid Continent International in the US (ICAO airport ID)
	This is what you would use on a flight plan

Internally the US still uses MCI to mean Mid Continent International for
flight plans but will accept either.

If you want to file an ICAO flight plan the K is required.

Now there's also IATA who refer to London, Heathrow as LHR which most 
travellers will know where ICAO refer to it as EGGG

Confusing eh???
