When it comes to airport codes, it’s important to know the information that they provide you with. Airport codes are three-letter combinations that are used to identify airports around the world. This allows travelers to easily recognize airports and determine which destination they are going to be traveling to.

The most widely used airport code list is the International Air Transport Association (IATA) airport code list. This list was officially adopted in 1947 and is based on the codes used by the US military prior to World War II. This list contains over 1,500 airport codes across the world.

In some cases, the IATA airport code list may not include all of the airports in the world. To include additional airports, some airports use the International Civil Aviation Organization (ICAO) airport code list. This list contains more than 5,000 airport codes and is used mainly for strategic and international flight operations.

When looking at a column of data, it is important to know what type of airport codes are included in the list. If the list contains airport codes in the IATA format, then the codes should consist of three letters. If the list includes airport codes in the ICAO format, the codes should consist of four letters. This information is important when trying to determine which airports are included in the list.

The airport codes are used in a variety of different applications and should be taken into consideration when sorting or analyzing data. Whether you are looking for a list of airport codes or are trying to determine which codes are included in a particular data set, understanding the format of the codes is essential.
