The airport code MCI is the designation for which city?

The airport code MCI is associated with Kansas City, Missouri. This three-letter designation is derived from the airport's name, Kansas City International Airport. Airport codes are established by the International Air Transport Association (IATA) and are used universally to identify airports.

In this instance, MCI effectively points to Kansas City, which is an important hub for various airlines, including Frontier Airlines. Understanding airport codes helps travelers easily identify their departure and arrival points, facilitating smoother travel planning and navigation through airport systems.

The other options refer to airports located in different cities, each with their own unique codes, which would not correspond to MCI. For instance, Orlando has MCO, Detroit is DTW, and Washington, DC, has DCA and IAD for its two primary airports. Therefore, recognizing that MCI specifically represents Kansas City, MO, is key in understanding airport designations.
