Jacksonville, Florida is represented by which airport code?

Jacksonville, Florida, is represented by the airport code JAX, which stands for Jacksonville International Airport. This code is derived from the city's name, making it straightforward to associate JAX with Jacksonville. Airport codes typically consist of three letters assigned by IATA (International Air Transport Association) and are often based on the name or a significant aspect of the city where the airport is located. In this case, JAX is an abbreviation that connects directly to the city it serves, providing a clear identification for travelers and airlines.

The other codes listed do not correspond to Jacksonville. MCI is the code for Kansas City International Airport, HSV is for Huntsville International Airport in Alabama, and AZO represents Kalamazoo/Battle Creek International Airport in Michigan. Each of these codes serves different airports in various states and does not relate to Jacksonville, which reinforces the clarity of JAX as the correct answer.
