Alaska Airline City Codes Practice 2026 – The All-In-One Guide to Master Your City Codes Exam!

The city code that represents Boise, ID, is indeed BOI. This code follows the standard practice of assigning three-letter identifiers to airports and cities, which helps streamline travel and booking processes. Each code is unique to a particular location, and in the case of BOI, it directly corresponds to Boise when looking up flights or travel itineraries.

The other codes listed do not match Boise; for example, BZN represents Bozeman, MT, while BRW is the code for Barrow, AK, and BET stands for Bethel, AK. Each of these codes is linked to different cities or airports, highlighting the importance of knowing the correct city codes when traveling.
