Which city is associated with the airport code ACV?

The city associated with the airport code ACV is Arcata/Eureka, CA. This airport, also known as Arcata-Eureka Airport, primarily serves the cities of Arcata and Eureka in Humboldt County. Airport codes are determined by the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA), and they often reflect the location or name of the city they serve. In this case, ACV is derived from the letters in "Arcata" and "Eureka," making it the correct designation for this region.

Additionally, Burbank, Binghamton, and Baltimore have their own unique airport codes that do not correspond to the ACV code, further confirming that Arcata/Eureka is the accurate choice.
