While Tableau can map most geographic locations, you may still encounter locations that are unrecognizable in Tableau, and therefore do not show up on your map. It is still possible to visualize this. One way to make this happen is by importing your location information along with its latitude and longitude coordinates into Tableau.
In this recipe, we will import custom geocoding to visualize where the busiest airports were in 2015:

Alternatively, you could get the data from the original source, www.world-airport-codes.com, and save it into a csv (comma separated value) file.
This is what the file contents look like:
