For the seasoned traveler or the occasional flyer, airport codes are like a secret language that opens the door to a world of destinations. Whether you’re jetting off for a business meeting, a family vacation, or a spontaneous adventure, understanding USA airport codes is the first step to navigating the skies with confidence. In this guide, we’ll demystify the world of airport codes, exploring their significance and highlighting some of the major airports across the United States.

What are 3 letter airport codes?

Airport codes, also known as International Air Transport Association (IATA) codes, are three-letter identifiers assigned to airports worldwide.

These codes serve as a shorthand way to reference specific airports and streamline communication in the aviation industry.

An IATA airport code, alternatively referred to as an IATA location identifier, IATA station code, or simply a location identifier, is a concise three-letter geocode used to designate numerous airports and metropolitan areas globally. These codes are standardized by the International Air Transport Association (IATA).


1. Location Identification:
Many airport codes are derived from the city or location they serve. For example, Los Angeles International Airport is known as LAX, where the “L” represents Los Angeles, and “AX” is simply a code assigned for identification.

2. Historical References:
Some airport codes have historical significance or are based on former names of airports. Denver International Airport, coded as DEN, is a straightforward abbreviation of its name.

3. Linguistic Considerations:
Certain codes may not directly correlate with the airport’s name or location. These cases often involve linguistic considerations, ensuring that the code is easy to pronounce and remember.

Now that we’ve unraveled the logic behind airport codes, let’s take a look of airport codes across the United States.
