What city is represented by the code IWA?

The city represented by the code IWA is indeed Phoenix, Arizona. This code refers to Phoenix Sky Harbor International Airport, which is the primary airport serving the Phoenix area. Understanding airport codes often involves knowing that they are typically derived from the city's name or the airport's location. In this instance, the IWA code is linked to Phoenix's broader metro area through regional naming conventions, which can include local nicknames or identifiers for the airport.

Indianapolis, Inglewood, and Atlanta each have their own distinct airport codes, none of which are IWA. Indianapolis International Airport is represented by IND, Inglewood is close to LAX known as Los Angeles International Airport, and Atlanta’s Hartsfield-Jackson Airport is coded as ATL. This further emphasizes the uniqueness of the IWA designation and its direct connection to Phoenix.
