Which airport code represents Austin, Texas?

The airport code representing Austin, Texas, is AUS. This code is designated by the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA) for Austin-Bergstrom International Airport, which serves as the primary airport for the city and surrounding areas. Airport codes are typically derived from the name of the city or airport, making AUS a logical choice as it includes the initials of ‘Austin’ along with an additional letter to distinguish it from other airport codes.

The other choices do not correspond to Austin. For instance, ATL is the code for Hartsfield-Jackson Atlanta International Airport in Georgia, AVL represents Asheville Regional Airport in North Carolina, and BOI is the code for Boise Airport in Idaho. Therefore, AUS is the only code that accurately identifies the airport in Austin, Texas.
