History of the Airport Identifiers. Anyone working for an airline would know, at least, the stations their company flew into. But you will enjoy some of the unusual Code Identifiers used by airports around the world. Some are down right comical. We also have a test at the end to see if your memory is what it used to be. Join us on Flight 184 as we depart the Gate Monday, October 6th at 7:00 pm EST. See you at the Gate.
