Where???

As a kid I could never understand why Americans referred to "Paris, France" until I realised that there are many towns and cities in the US named Paris, so they have to be specific about which they are referring to.  This came to mind the other day when I read a story about a local couple who booked a flight from Birmingham to Trinidad only to find when they got to Birmingham International Airport that their tickets were for a flight to Trinidad from Birmingham, Alabama!
