First, go to the website World-Airport-Codes.com. Once you have entered the site, type the name of the airport you are looking for into the Search box. Alternatively, enter the city in which the airport is located.
Once you have entered your search terms and clicked Search, you will be directed to a list of results that are possible matches for your query. If you search by airport name, the results list will show only one airport. If you search by city, the list might contain several results, as many major cities have more than one airport.
Beside the name of the airport, the results show the International Air Transportation Association code as well as the city and country in which the airport is located. The International Air Transportation Association code is the same thing as the airport code. It is a three-letter airport designation used to facilitate air travel and reduce the potential for communication errors.
If you click on the name of the airport in your search results, you will be directed to a page with detailed information about that airport. Some of this information includes the airport's main phone number, time zone, history and destination list. Some pages even have photographs of the airport.
