If you are traveling and see the letters LAX, you may automatically know that they are the airport code for the airport in Los Angeles, California. But, do you know what CAK stands for? The code letters given to airports throughout not only the United States but also throughout the world have a very specific purpose and are used not only for communication but for safety issues as well. Definition A definition of the airport code: The three letters of the code serve as a location identifier that is recognized by airports, governments, and security officials all over the world. Every airport has a different code that is unique to it. How Do Airports Get Their Codes? It can be a very simple process, such as in the case of the Atlanta, Georgia airport-its code is ATL. However in cities with more than one airport or for multiple cities that are served by the same airport, or for cities that have the same beginning it gets a little more tricky. For instance, the Dallas/Fort Worth airport code is DFW. Sometimes the letters match the name of the airport like JFK for the John F. Kennedy Airport. At other times, the airport is given an airport code that relates its position east or west of the Mississippi. With the growth throughout the world, and the increase in the number of airports there are some changes being made to the coding system. Now, some airports have 4 letters in their airport code or a combination of letters and numbers to designate them. What Is The History Of The Airport Coding System? Back in the early 1900s the National Weather Service assigned two letter codes to different areas and cities for easy reference and to record weather information. The first three letter coding system was started back in the 1930s by the International Air Transport Association (IATA.) In the 1930s as airports began to spring up across the world, a need for an airport code became evident. For those areas that already had a two letter weather code, the letter X was added to the original two letters to make the new code-hence, LA became LAX. How Is The Airport Code Used? Travelers use it when they are making reservations for flights and when they are at the airport to check for flight times, cancellations and delays. Airline workers such as baggage handlers and check-in attendants, use it to get your luggage on the correct flight. Pilots use it to notify those who are watching radar of their destination. The airport code keeps passengers connected with their luggage, and also keeps the communication between airports, security personnel, travel agencies, consistent and organized. Are There Any Other Special Rules? Yes, there are many other rules about how the codes are assigned, but one that you might find interesting is that the United States military petitioned the government to have a special airport code system designated for them. Now all military airports have an additional letter on the front. For instance, Navy airports all have an N at the beginning of their code. Airport coding is something that most of us never think about and probably take for granted a lot of the time. But the truth is, that it has made air travel easier not only for the passengers but for the airline workers, pilots, controllers, and so on. It allows people in different locations, who may speak different languages, to have a basic understanding of the travel system. So, the next time you fly, take a minute to think about the advantages of the coding system. |
