"Most" applications.  An airport has a Location, but it also has an
address.  That address has a Zip Code.  If you include the type "Zip Code"
and the type "Location", which lat/long are you going to get, the one for
the airport, or the one for the zip code centroid?  That might not make
any difference for calculating UPS shipping rates, but it sure as hell
makes a difference if you're flying there.
