As a side note - all the IATA codes are unique for each airport - wouldn't it be better to use these as the Primary Key and Foreign Keys? Then you wouldn't have to even join the tables unless you wanted the port names (not just the code)
This is true, but FWIW, my application will mostly be joining for the name of the airport or the city, not the code.
I'll keep the idea of using the codes as keys in mind, though. Thanks for pointing that out.
