Airports aren't allowed on my list if I haven't landed there.

Why not make this field a 4-character field, so that you can designate the previous use of a code with a suitable suffix (e.g. BKKX, HKGX, etc)...

For non-aviation enthusiasts, 4 letter codes are difficult to comprehend.

...ah, no, I didn't mean the ICAO codes, they would indeed be baffling, even to some of us enthusiasts! No, I just meant where you might have BKK twice, for example, you make the current one BKK, and the previous airport BKKX. I note that this is what www.flightmemory.com do, so that when you enter historical data you can determine which was the correct airport at the time.
