Alaska Airline City Codes Practice

The airport code that stands for Helena, MT, is HLN. This code follows the International Air Transport Association (IATA) standard format, which assigns three-letter codes to identify airports globally. HLN is specifically designated for Helena Regional Airport, which serves the city of Helena in Montana. The code is derived from the name of the city itself, making it intuitive for travelers familiar with the region.

In contrast, the other codes represent different cities and airports unrelated to Helena. For instance, EWR is the code for Newark Liberty International Airport in New Jersey, LAS represents McCarran International Airport in Las Vegas, Nevada, and RNO stands for Reno-Tahoe International Airport in Reno, Nevada. Each of these codes is distinctive to their respective locations, highlighting the importance of understanding IATA codes for identifying airports accurately.
