Seems pretty simple to me, importance is going to be partially
subjective, even if 2 airports have similar number of flights, some
will have 747s & 380s and some won't.

highway=* classifications seems at least partially subjective as well.

I see the need for at least 4 or 5 airport types, major international
airports, minor international airports, regional airports, tiny
airports and airstrips.
