I looked into the data a bit more.
It seems that only the States of USA are in the data.
However when I looked at the province code for other airports there appears to
be some sort of grouping - I'm not sure if it can be mapped directly to
I'll hunt around and see if I can find some data elsewhere. The only problem
is that most of the data one finds online is not very complete.

That's a good idea - thanks.
I looked at just using the 2 letter prefix in the ICAO code to map the
airports to countries but that is not so straight forward.
For instance some countries have multiple ICAO prefixes.
Another interesting discovery is that there are lots of countries that share
an ICAO prefix for navaids and waypoints.

Looks like a new field in the airport DB would be a better idea.
